Size beware

Tiny size 6.
I never imagined that adult undies size 6 would be as small as the smallest child size! Double check measurements!! My daughter is skinny but going from youth to adult undies is not as simple as starting at smallest size.

An eco-friendly choice

I ordered one size down and they work perfectly. They last through the night, even on heavier days. You just have to rinse them by hand until the water runs clear before putting them in the washing machine, and avoid using fabric softener so they’ll last longer (mine have lasted a couple of years with only a slight fraying of the elastic waistband).

These are relatively large bikini style undies, but they work as described.

I bought these for me but my daughter nabbed them and has just raved about how amazing they are. No leaks at all and she said they are very comfortable. I’ve ordered a few more as they do need to be washed and allowed time to dry. Highly recommended!
