Boy short panties are a type of women's Underwear that covers the hips and upper thighs, like a pair of close-fitting Short Shorts. They are a relatively new, but increasingly popular style of lingerie among women as a modest and comfortable alternative to conventional Panties or the Thong. Essentially the female version of Boxer Briefs.
Boyshorts are commonly worn with a Camisole as Loungewear, or with a Sports Bra as Sportswear.
