The boyshort lace hipsters with the smooth upper band stay in place without rolling down, versus the ones with the lace all the way up. I've purchased both styles, and from now on will only get the ones with the band at the top. They are comfortable, and surprisingly make the tummy a little sleeker. These styles are made to ride up into the butt cheeks just a little, in order to give you a nice shape and no panty lines, so if you don't think you'd like that, these aren't for you. If you can handle the little bit of ride up, you'll love these!
