The details are everything on this classy black lace bra set from French brand Lou. First there are the adorable buttons, which you'll find front and center on the bra as well as on the back of the thong. Then there's the lace, which is surprisingly unique and quite stunning visually on the body. Finally, there are the little mesh-lined slits that show off hints of skin where you wouldn't expect any normally. All in all, this is one of our favorite new sets for fall.
