keeps my thighs from chafing and my butt dry
I used to wear my partner's briefs or biker shorts to prevent chafing and sweat marks on seats but it limits me to wearing flowy dresses to hide the lines. It's nice to finally have something designed for the woman body that is smooth (no lines) and has no shapewear features. I went back and bought four more pairs so I can wear dresses all summer long.
