Great underwear for adults too!
I am 5'2", 110 pounds and have a lot of trouble finding underwear that don't give me a wedgie. This is because I have a small waist and skinny legs but a rather large behind so finding anything that will fit and won't ride up is always a challenge. In pants, I am usually a size 1 in juniors (if the behind area is really stretchy), otherwise I wear size 2 in petites. I bought both the knixteen boyshort and knixteen bikini leakproofs in a medium size based on other reviews I read. The boyshort fits PERFECTLY and doesn't ride up at all, stays perfectly in place! The bikini will stay in place if I am wearing pants but will ride up with shorts or a dress. I think it's because the leg holes are quite large and the material is soft and after a few hours of wearing they stretch a little and start to ride up on me. They are both quite comfortable and feel very thin, like normal undies. The leakproof function also actually works! Although I would recommend them for backup and not as a main period product if flow is heavy. I bought five pairs total to last me the week and do not regret it at all. Would recommend the boyshort!
