I've never had much luck finding boyshorts that fit me properly. I took a chance on these and am glad I did. They are so comfy and I like that they don't have a seam going right up the front. They do, however tend to slip down in the back and occasionally need to be pulled up. They were already slightly loose when I first put them on and were even looser by the end of the day. I am a size 18 and got the 1. I wish there was an option for one size smaller, but am still happy with the ones I purchased.
