    Not just for teens

    I've been wearing the usual boyshorts and bikini styles for years and recently decided to try out this teen light leak proof no-show boyshort for the first time during the anniversary sale for just $13 and they're great! I usually wear a regular medium but sized up to a large for the teen. Note: I'm not very curvy in the hips or butt, not sure if maybe that's why the teen style works for me. I plan on trying more in the near future as they're more economical and have different color and pattern options!

    Perfectly seamless and comfortable.

    Will never be able to wear anything but these underwear. Very comfortable, wash well, do not stretch out, do not slide down and completely seamless/ no show.
