For the price of these, I wasn't expecting anything amazing. However they fit me like a glove! I will say though, that I have a... well. Flat booty. I wear a small underwear. And size 1-3 Jean's depending upon the brand. They are so cute and comfy! I thought I might feel a tad uncomfortable in the open back, but I didn't! I barely noticed unless I was looking directly at them. Hubby approved. 10/10 would purchase again!
