There are now quite a few brands making comfortable and cute plus-size underwear out of natural and eco-friendly materials like organic cotton and hemp. And we’ve done the research for you and compiled them all in a list for you here!

What To Look For in Organic Plus-Size Underwear
We all know how important it is to take care of our hu-ha health. Prioritizing natural and organic fabrics can help us do that in a few ways.
One, natural fabrics are more breathable. Keeping things dry down there helps to prevent bacteria overgrowth and yeast infections.
Not only that, but a lot of synthetic fabrics contain chemicals (like phthalates for example) that can be toxic to human health, especially when they accumulate in the body for long periods of time.
Lastly, many fabrics are finished with permanent chemical finishes, including fabric softeners, petrochemical dyes, formaldehyde, and volatile organic compounds (VOCs). If you see underwear or other articles of clothing that have labels such as “wrinkle-free,” that should be a big red flag for you, indicating that the fabric has been treated with one or more of these groups of chemicals.
This is why most OB-GYNs highly suggest stocking your underwear drawer with natural materials like cotton. BUT, organic cotton is even better than conventional cotton because it’s grown without the use of toxic herbicides and pesticides.
So look for third-party certifications like Global Organic Textile Standard (GOTS) organic cotton and OEKO-TEX, which indicates that the product has been tested for a long list of potentially toxic substances.

Third Love has become pretty well known for their campaigns promoting bras and underwear that actually fit. Most of their products are made with synthetic fabrics, but they do have an organic cotton collection that includes briefs, thongs, and bralettes.
Duluth Trading Co.’s “Free Range” organic cotton briefs, boxers, and bralettes are made using their “Stay-Put Fit” so things don’t move around and get bunched up throughout your day. These really are as comfortable as they claim to be!

The team puts a lot of thought into each and every step of the production process in order to make sure everything is as ethical and sustainable as possible.
They carry briefs, bralettes, and shorts. We love their colors!
Honorable Mention: Tomboyx
Tomboyx doesn’t use organic fabrics for their underwear, but this brand makes the list as an honorable mention for a couple of reasons.
First, their sizing has one of the widest ranges we’ve found, from 3XS to 6XL.
Second, they have a really wide variety of styles—so whether you prefer briefs, thongs, long boxer briefs, or something else, you can get what’s comfortable for you.
Third, even though they don’t use organic cotton, they do use OEKO-TEX certified natural cotton, which is better than most synthetics.
They also have a TENCEL collection, which is another great option for a non-toxic fabric. Although it technically qualifies as a semi-synthetic, TENCEL is manufactured from plants using a closed-loop process, which means no potentially toxic chemicals make their way out of the manufacturing process and into the environment. Check out this article for more info on that.
Choosing natural, organic, eco-friendly, and size-inclusive underwear is better for your health and better for the future of our planet.
