I’m typically a regular size Medium, waist 32 inches. But I do have a little junk in the trunk and meaty thighs so I went for the Large shorts, thinking they might shrink if too large. They actually fit just perfectly, look great, and love with me so that I can be active in them and not have to worry about tricky or delicate fabric. So comfortable, in fact, that I don’t mind going commando in them, and often do.
