    Boyshort

    This cut is my favorite cut ,and love how it’s seamless as well. I am usually a large and with the knix undies medium is a better option for me.

    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!
