Welcome to the ultimate showdown at yummie! We're diving into the timeless debate of cotton vs nylon underwear. Is cotton underwear best? Or nylon? What sets them apart? Which one should you choose for your comfort and style needs? Buckle up as we explore the unique features of these two underwear superheroes.

Both nylon and cotton underwear have their unique perks. Choose nylon when you need a sleek fit and moisture-wicking magic. Opt for cotton when you prioritize comfort, breathability, and natural fibers. The best part? You don't have to pick just one! Mix and match to suit your lifestyle and enjoy the best of both worlds.

Cotton is the champ of breathable underwear (and moisture-wicking underwear, absorbing and thereby wicking away moisture from the skin, keeping you comfortable). They’re absorbent and help prevent irritation, especially during hot summers. Yummie’s cotton undies come in a substantial cotton fabric with level 3 shaping. Below we’ve picked some of our favorite pairs.

Joy Cotton Shaping Brief

This comfortable underwear features a high rise with a wide, 2-ply waistband that delivers targeted shaping at the tummy. The sideseam-free construction of our Cotton Brief ensures you’re comfy for the whole day.

Alex Cotton Shaping Thong

Some days you’re in the mood for a brief, and some days you’re in the mood for a thong. On thong days, this figure-flattering underwear is your go-to. Our Cotton Thong is great under jeans, like our Bootcut Jeans, Straight Jeans, Ankle Jeans, and Skinny Jeans (which only have limited options and sizes left, so hurry!)

Check out some of our other comfy cotton staples, like our Jules Cotton Rib Bra Top, Talia Cotton Shaping Capri, Mel Cotton Shaping Bike Short, and Ruby Cotton Seamless Bodysuit. You’ll also love our Cotton Rib Hoodie with matching Cotton Rib Cropped Pant.

Is nylon good for underwear? That’s a resounding yes. Nylon is smooth and silky, dries quickly, and is more lightweight than cotton. It’s an ideal fabric for shapewear because it retains its shape and lies smoothly under clothing. We grab nylon undies to wear under pants and skirts, especially any with clingy fabrics.

Ultralight Shaping Brief

Our Ultralight line offers level 2 light shaping and targeted tummy support in the wide, 2-ply waistband. It’s a best-seller for a reason – grab this everyday staple in a brief or pick up our Ultralight Shaping Short, Ultralight Shaping Thong, or Ultralight Girlshort. We love how our pants and skirts glide over this smooth, lightweight fabric!

For lighter level 1 smoothing, try our Comfortably Curved Smoothing Thong or Smoothing Short. For firmer level 3 shaping, check out our Mona Shapewear Short, Fran Shapewear Thong, and Sage Shapewear Brief.

Seamless Solutions Shaping Bottoms

When considering nylon underwear vs cotton, one of the benefits to nylon is its shaping power and stronger compression. Our Seamless Solutions line for special occasions delivers firm level 4 compression that’s comfortable enough to wear all day. Try our High Waist Short with Rear Shaping, High Waist Brief, or High Waist Thong, all with soft silicone at the edge to prevent slipping.
