I would love for the womens underwear to stay put and not ride up, stretch out, or go into wedgie-land. I have a fuller tush and have tried both the Womens Hipster and Boy Shorts, and I think if an elastic band around the bottom part of the leg was added, and maybe a little more material in the cheeks area of the Hipster, they would stay happily in place. Although I normally wear Bikinis, no way there is enough material regardless of size for my fit, and I'm a small. As it is, although cute, I don't wear the Pact undies I bought because they don't fit my smaller waist, curvy rear. Suggestion- A cut from another brand that works well for us curvy tushes is Womens Hanes Ultimate Cotton Stretch in regular or the cute lace around the wide top waistband. Both have elastic around the leg holes to keep in place. Their Bikini is still my go to for best fit. Thanks!
