Finding Clothes That Are Actually 100% Cotton

Good cotton clothing is still being made. Companies that have been weaving and sewing it for a century are still at it, the fabric is better documented than it has ever been, and once you know which lines to look for, a full wardrobe of pure cotton is within reach at ordinary prices.

The reason it takes a little knowledge is that elastane has become the default. It is usually 2 to 5 percent, printed in small type on the tag, and it is what makes a garment stretch. Spandex, Lycra, and elastane are three names for the same fiber, a polyurethane, which is to say a plastic. Synthetic textiles shed fibers during wear and washing, and those fibers turn up in water, in air, in soil, and in human tissue. What that means for human health is still being worked out, and I am not going to tell you it is settled.

What I can tell you is that cotton is comfortable, it breathes, it washes hot, it stays fresh, and it ages into something better than it started as. That is reason enough. Here is where to find it.

Reading the label

Fiber content is printed on the tag, and two phrases are worth learning. "Exclusive of decoration" and "exclusive of trim" mean the stated fiber content covers the main fabric only, so the waistband, elastic, thread, and lace are counted separately. In a store you can check a garment in about five seconds. Online that language is often left out of the listing entirely, or buried far enough down the page that you have to go looking for it.

Filtering a website for 100% cotton will still hand you garments with elastic waistbands, since the filter reads the fabric field and the waistband lives somewhere else in the listing. Sometimes it is not in the listing at all. On a flat product photo an elastic waist is very hard to spot, so look for a gathered or shirred back panel, search the page for the words elastic, stretch waist, or pull-on, and read the customer photos and reviews, which is often where it finally turns up.

New cotton arrives carrying chemical sizing, the starch and synthetic resin coating applied during weaving so the yarn runs cleanly through the loom. It is what gives a new shirt that crisp, faintly stiff hand. For sensitive people it is worth taking seriously, since formaldehyde-releasing resins and the other finishing chemicals are a recognized cause of textile contact dermatitis, and a rash that starts with a brand-new garment often traces back to the finish rather than the fiber. Most of it comes out over the first two or three washes, so launder anything new before it touches your skin, and wash it more than once if you react easily.

Solid colors are your friend. Heathered and marled shades are usually blends even within a line that is otherwise pure cotton. The Hanes Beefy-T is a clean example. Solid colors are 100% ring-spun cotton, while ash is 99/1 cotton-polyester, light steel is 90/10, and charcoal heather is 60/40. Same shirt, same tag design, different fabric.

"Cotton-rich," "cotton blend," "performance cotton," "comfort stretch," and "flex" all signal synthetic content. When you see those words, keep browsing.

Rashes at the waistband, bra band, and sock cuff

For some people this goes beyond preference, and there is a satisfying amount known about it.

Contact dermatitis that appears exactly where the elastic sits is well described in the dermatology literature, classically across the back in the pattern of a bra band. Spandex, Lycra, and elastane are the same polyurethane fiber, and the fiber itself has not been established as a sensitizer. The culprits are usually what travels with it: rubber and rubber-processing chemicals, including thiurams, carbamates, and mercaptobenzothiazole, along with disperse dyes and resin finishes. Patch testing identifies which one, and that answer is genuinely useful, because it tells you whether you need to avoid elastic entirely or only certain kinds.

If you have a natural rubber latex allergy, work from the assumption that the crossover applies to you. Latex threads are routinely added to spandex garments, most often in sewn-in waistbands, and the fiber percentage on the tag will not reveal it. People who react to latex frequently react to spandex, Lycra, and elastane items for exactly that reason. Latex allergy is an immune response to proteins in natural rubber and is not limited to the skin, so read plastic-free marketing closely: some products solve the plastic problem with natural rubber. Latex-free, spandex-free, and elastic-free are three separate claims, and knowing which one a product is making tells you whether it fits your situation. One observation from my own practice, offered as an anecdote and nothing more: I have seen more latex allergy in patients carrying the 4-3-53 HLA-DR haplotype. That is a pattern I have noticed, not a published finding.

Healthcare workers should pay particular attention here. Reported prevalence of latex allergy runs around 9.7% in healthcare workers against roughly 4.3% in the general population, and NIOSH and OSHA cite sensitization rates in the 8 to 12 percent range. Dental personnel have been reported higher still. It comes from glove exposure accumulated over years, and it follows you home. If you spent a career in gowns and gloves and you now get a band of dermatitis under your bra or at your sock cuff, that history is worth telling whoever is patch testing you, and it often shortens the path to an answer.

Jeans and pants

Wrangler makes a full line of 100% cotton non-stretch denim, including the Cowboy Cut, in men's and women's fits. Rustler is Wrangler's budget label, sold mostly at Walmart, and the rigid version is raw 100% cotton denim for around fifteen dollars, which is remarkable for what you get.

Madewell is the other place to look, at a different price point and with a wider range of cuts. Their denim is sorted by fabric type on the site, and the category to choose is Rigid, which is 100% cotton with no stretch. The Flex, Airy, and Everyday fabrics are the stretch ones. Rigid comes in women's and men's, in petite, tall, and curvy fits, which is more range than most non-stretch denim offers.

Madewell also names the mill on the individual product page, which almost no brand does, and the names that come up are worth recognizing. Cone is the historic American denim mill, weaving in North Carolina since the 1890s. Candiani is the Italian mill that built its reputation on cutting the water and chemical load out of denim production. Kaihara is the Japanese mill that supplies much of the world's best denim and still dyes its own yarn. Any given pair uses one of them, and the lineup rotates, so read the fabric line on the style you like. Madewell also flags when a style is cut at a Fair Trade Certified factory or made with regenerative-certified cotton. You are buying a plain cotton jean, and you are buying one whose supply chain is on the record.

Carhartt work pants divide along one simple line. The firm duck styles, including the B01 double-front that has been in the catalog since 1939, are 12-ounce 100% ring-spun cotton duck. Anything labeled Rugged Flex has spandex woven in, usually 1 to 3 percent, which is the purpose of that fabric. Choose by the fabric name and you will get what you want every time.

Two smaller American makers are worth knowing, and they sit at different points.

Round House has been sewing in Oklahoma since 1903 and builds its jeans, dungarees, and bib overalls from 100% cotton duck and denim, mostly in the sixty to eighty dollar range. For American-made pure cotton at that price, the value is remarkable.

Pointer Brand, made by L.C. King in Bristol, Tennessee, since 1913, works in cotton duck, denim, and hickory stripe out of what is reportedly the oldest continuously operating cut-and-sew factory in the country, and it costs more. What you get for it is styling. Their chore coats and hickory stripe pieces have a following well outside the workwear world, and the cut and detailing are sharp enough to wear anywhere.

For work pants, Filson runs from cotton twill and canvas up through Tin Cloth, which is 100% cotton and some of the sturdiest fabric made in it. The construction is excellent throughout, and it is the same oil-finish cloth as their jackets. Parts of the current line have stretch added, so read the fabric listing on the individual style.

Rigid denim and firm duck are stiff for the first few weeks and then mold to you. That is the whole appeal, and it is why the raw denim people prefer it.

Levi's deserves its place in any cotton conversation, since the 501 has been made in 100% cotton since 1873 and still is. The same fit now also comes in a 98/2 stretch version, so check the specific wash you are buying.

Warm weather is easier than people expect. Filson and Wrangler both make shorts in 100% cotton, and any cotton pant you already own can become a pair of shorts with two cuts. Cotton takes well to being altered, which is one more thing it has over performance fabric.

Shirts

The blank tee brands are the easiest place to start, because they publish exact fiber content for every color. The Hanes Beefy-T is 100% ring-spun cotton in solids and costs a few dollars. Gildan Ultra Cotton, style 2000, is 100% US cotton in solids, and they list the exceptions plainly: ash is 99/1, sport grey and the antique shades are 90/10, and the heather and safety colors are 50/50. Comfort Colors 1717 is 100% ring-spun cotton, garment dyed, heavier and softer from the first wear, and it runs large enough that most people size down. All three are sold blank in bulk through screen printing suppliers, which is usually cheaper per shirt than retail.

Carhartt belongs on this list too. The K87 pocket tee, in production since 1992, is 100% cotton in most colors, with the heathered and specialty shades being the blends. It is heavier than a standard tee and it holds up to real work.

L.L.Bean is one to consider for cold-weather shirts. The Scotch Plaid flannel is 100% cotton woven in Portugal, and the chamois shirt, which the company has made since the 1920s, is heavier still and also pure cotton. Both wear for years and get softer as they go. The styling is drab and out of date, which is either the appeal or the drawback depending on who you are. Lands' End covers similar ground in oxfords, chinos, and cotton knits at a comparable price.

For woven shirts, Madewell's poplins, chambrays, and oxfords are frequently 100% cotton, though their jersey tees and knits often have stretch, so read the fabric line on the individual item. Filson makes cotton twill and canvas shirts built to outlast several rounds of anything else. Oxford cloth button-downs in general are commonly 100% cotton.

Free People is worth a look if you want something with more flair. They carry a lot of 100% cotton in their woven tops, dresses, and skirts, priced moderate to expensive, and the styling runs from boho to outright clownish depending on the garment. Plenty of their line is blended, so the fabric tag is doing real work here, but when a piece is pure cotton it will say so.

If you want something printed or embroidered, many Etsy sellers work on 100% cotton blanks from the same brands listed above, and most will tell you which blank they use if you ask.

Hoodies and sweatshirts

Most hoodies on the market are a cotton-polyester fleece, usually 50/50 or 80/20, so this is a category where knowing one name saves you real time. Carhartt is a useful illustration that fabric varies by category within a brand: their tees and duck pants are cotton, while their midweight hooded sweatshirts run around half polyester depending on color, with spandex-reinforced rib knit at the cuffs and waist.

American Giant is the one to know. Their heavyweight fleece is 100% combed ringspun cotton grown in the Carolinas, knit and sewn in the United States, and the Classic Full Zip is the piece the brand was built on. It is heavy, around 12 ounces per square yard, and it lasts for years rather than seasons.

Socks

Socks are the category where the specialty makers earn their keep, because nearly everything on the shelf uses nylon for durability and elastic in the cuff. The Cottonique socks are thin and shapeless, so know that going in.

Cottonique makes an elastic-free style in 100% organic cotton that is supposed to stay up by knit construction alone, and Rawganique builds all of its socks that way. They are the two places I know of for a true one-ingredient sock.

Darn Tough is my own pick if you can tolerate a small amount of Lycra. Some people react less to them than to cotton socks, they are knit in Vermont, and they carry a lifetime guarantee. The Lycra runs 1% to 4% depending on the style, and the pattern is consistent: the heavier cushioned socks use the least. Their tactical over-the-calf extra cushion is 79% merino, 20% nylon, and 1% Lycra. The hiker boot socks sit at 66, 32, and 2. Work and midweight styles are typically 3%. The ultra-light and no-show styles go to 4% and also drop the wool toward 45 to 51 percent. So the heavier the sock, the more wool and the less Lycra. They list the composition on every product page, so check the style before you order.

Underwear and bras

This is where reading the trim line pays off most, since plenty of organic cotton underwear still has an elastane waistband on it.

Start with Madewell if bras are what you are after. Their wire-free bralettes are the best-looking cotton option in this whole category, and they come in real styles rather than clinical ones. Some are 100% cotton and some are blended with Modal and spandex, so check the fabric line on the specific style, but the pure cotton ones are there and they are worth the search.

Cottonique makes underwear, bras, and loungewear in 100% organic cotton. Most styles have elastic at the waist and leg openings, and that elastic is latex-free, spandex-free, and wrapped in cotton so nothing synthetic touches the skin. If you want none at all, they make elastic-free styles as well, including a drawstring panty. Check the individual product page and you will know exactly which version you are getting. The styling is frumpy, and there is no getting around that. It is medical-grade practical rather than pretty, which is a fair trade if your skin has been telling you to make it.

Rawganique makes everything without elastic, in cotton, linen, hemp, and merino. The brand has a crunchy bend to it, hemp and compostability and all, and the clothes look the part. What they are selling underneath the marketing is real: single-fiber garments with nothing added, which is exactly what you came for.

Kent makes organic pima underwear that is compostable, with a clean, modern aesthetic.

Bras take the most patience, since the band support is what the elastic is doing. Cotton and merino wool versions exist and fit differently than what you are used to.

Swimwear

Swimwear is the hardest category in this whole piece, because cotton and wool both lose their shape when wet. That is the reason elastane took the category over, and most of what gets marketed as natural swimwear still runs 2 to 8 percent.

Industry of All Nations is the exception worth knowing. They make board shorts and boxers in pure cotton, dyed with naturally fermented indigo, and several of their drawstring board short styles have no elastic in them at all. Not every variety qualifies, so read the individual listing, but a fully cotton swim short is a real thing you can buy.

For a fitted women's suit, Pure Earth Collection is the closest I have found, at 2% Lycra. Below that, you are crocheting your own.

Coats

Filson is the reference point here, because their answer to weather is an oil finish rather than a synthetic membrane. The Tin Cloth line is heavy waxed cotton, dense enough to shed rain and stiff enough that it takes a season to break in, and the same waxed shelter cloth runs through their jackets and vests. It is repairable, rewaxable, and it lasts long enough to get handed down.

Their Mackinaw line is 100% virgin wool, a different natural fiber solving the same problem, so it is worth knowing which one you are choosing. As with their pants, some newer styles have synthetic content or stretch added, so read the fabric listing. Waxed cotton and wool both ask for a little care, and both give you decades in return.

My favorites, and I say this as a former garment inspector:

Madewell, at the moderate end.

Filson, at the expensive end. Buy-it-for-life quality, priced accordingly.

Wrangler and Rustler, terrific value at the inexpensive end. Round House belongs right there with them.

Hanes, Gildan, and Comfort Colors, all well made. Gildan is probably the best value of the three.

American Giant, the best pure cotton hoodie I know of.

Darn Tough, the best sock, though it involves a small compromise of between 1% and 4% Lycra.

Iron Heart, if you want the white whale of cotton jeans. A major splurge, heavyweight Japanese selvedge, and the kind of denim you hand down.
