A few years ago, I started transitioning my wardrobe to mostly cotton pieces. But as I made that shift, I realized there was one area I hadn’t really paid attention to—my undergarments. So recently I’ve been hunting for non syntheic materials like cotton (and plastic-free whenever possible) for bras and underwear.
Why cotton? Because these pieces sit directly on our skin for hours—sometimes all day. And when we’re active, sweating, or just going about our routines, our skin is absorbing whatever touches it. I wanted my most intimate layers to be as gentle and breathable as possible.
But comfort shouldn’t cost a fortune—so I’ve been searching for mostly affordable, cotton options that actually fit well and feel amazing.

Target’s Cotton Underwear & Bras – These have become everyday staples. I love the simple cotton hipsters and bralettes—they’re soft, breathable, and easy on the wallet. Comes in so many colors and prints! I’ve owned the Jockey line for some time and it’s great quality. Auden is new to me but I’m loving it so far! And honestly you can’t beat the price, it’s so good for cotton fabric!

Pepper Bras – Slightly pricer but so worth it! When I first discovered them, it felt like someone finally understood my body. I’d spent years settling for ill-fitting bras that either gaped or squished—but Pepper? Total game-changer. Their bras are designed specifically for smaller cup sizes, and they just get it. So when they released their Supima Cotton Wirefree Bra, I didn’t hesitate. It sold out fast (there’s often a waitlist!), but the moment it came back in stock, I grabbed it. And wow—it did not disappoint. This bra is made from a luxurious cotton blend (Supima cotton, modal, and a touch of lycra), completely wire-free (a must for me), and comes with removable padding. It’s honestly like slipping into your favorite worn-in tee: soft, breathable, and so comfortable that I often forget I’m wearing it. It gives just the right amount of support and coverage while feeling weightless—like a second skin.

Switching to cotton bras and underwears has been one of the best decisions I’ve made for my wardrobe. They’re better for my body, more comfortable for daily life, and they give me peace of mind knowing I’m choosing fabrics that feel good in every sense of the word.
