I don't care how hot your body is, showing your butt crack is not cute. And don't let your plumber boyfriend tell you otherwise.
Miss Oops JAKs is made for those whose buttocks cleavage shows when they bend down or sit. And that's not everyone. I, for example, have a long torso, so rarely do I have this problem. There are two options for those who do have this problem. You can either never bend over or you can get this handy stretch lace band, which goes over your pants and under your shirt. It appears to be a lace camisole, but really, it's a neat, butt-crack stopping tool. Just say no to BC!
