Seamless Underwear for Leggings
To avoid panty lines under leggings, wear seamless underwear with bonded edges, ideally a thong or a wide-sided hipster, in your true size and a shade close to your skin tone.

Why lines happen
Sewn elastic edges press into skin and create a ridge. Too small a size makes it worse, because the edge digs in.
What works
- Bonded edges. Laser-cut, glued edges lie flat. See seamless underwear.
- The right cut. A thong has no back edge; a hipster spreads the side edge over more skin.
- Your true size. Check the size chart.
- Skin-tone shades. Nude light or nude deep under light leggings.
