Backless bras are quite a controversial subject. For starters, do they really do anything? And wouldn't it just be easier to go braless? It's a yes to both for us, which proves exactly why this is such a tricky lingerie item to pin down and feel content with. So if you're in need of a bit of support and don't want to feel exposed (not to mention if you have a fuller bust), there are definitely outfits that require such an item. Whether that's a plunging top, dress or jumpsuit, a backless bra can come in handy and really make your whole look.
