Quick answer

Choose cotton for everyday comfort and breathability; choose slipper/grannysmith for a semi-sheer, sexy look with a soft, textured feel.

Cotton: The everyday staple

Cotton undies like the High-Rise Undies in gym are made from organic cotton with a touch of spandex for stretch. They offer a body-skimming fit that stays put without cutting into your curves. The fabric is soft, breathable, and ideal for all-day wear under jeans or trousers.

Slipper/grannysmith: The sheer, textured option

The slipper/grannysmith fabric is a semi-sheer, organic cotton pique knit with a matte/dry hand and loads of stretch. It’s used in the Matilda Thong and Lorna Undies for a lower-profile, sexy look. The texture adds visual interest while remaining breathable—perfect for when you want a little more style without sacrificing comfort.

Trade-offs to consider

Cotton is more opaque and forgiving for visible panty lines, while slipper fabric is semi-sheer and may show more. Slipper fabric has more stretch and a drier hand, which can feel less clingy than cotton. If you prioritize coverage and no-show, go cotton. If you want a barely-there feel with a touch of allure, choose slipper.

How to decide: Cotton vs Slipper

  • Choose cotton if: You want maximum coverage, opacity, and a classic soft feel. Cotton undies like the High-Rise Undies in gym are best for all-day wear under any outfit.
  • Choose slipper/grannysmith if: You want a semi-sheer, textured look with loads of stretch. The Matilda Thong and Lorna Undies are perfect for a sexy, low-profile vibe.
  • Consider both if: You like variety in your underwear drawer. Cotton for everyday, slipper for days when you want a little more style without compromising breathability. Start with one style in each fabric to see which you reach for more.
