I am a curvy 5'2" 145 pounds (who usually wears a M) and bought an XL based on the size chart. The XL are a little loose, but don't ride up or bunch. They fit smoothly under even my yoga pants, and stay in place nicely. I usually wear a high cut brief style, but went with the WAMA hipster as the closest available option. I was concerned about the 'cheeky' description, but the hipster is not making a wedgie. An unexpected bonus is that the front of the hipster leg opening doesn't dig into my leg crease. The back elastic waistband sits a little lower than I generally like, but I am getting used to it. Overall, I find this style comfortable and will order a few more pairs but will check out the L first . The trial pair I bought washed nicely - no shrinkage, and they are quite soft and comfortable. I actually find myself looking forward to wearing them when they've come out of the wash.
