KTLA in Los Angeles is reporting that a local clothing story, American Rag, has installed an "ass cam" in their dressing rooms so that you can see how your butt looks in jeans. It's a big deal for both men and women. You always want to be sure that your ass looks good in a pair of jeans before you buy them. This little invention might just do the trick. After all, is you ask the sales girl in the store they are always going to tell you that the jeans look good. More after the jump.
