Have you seen a low-back bra converter? It’s a clear strap that wraps around your waist. Genius.
You wear a normal bra. Then you clip this invisible band around your belly. The straps vanish.
It looks like a weird belt. But under a dress? Flawless. You get support and a smooth back.
One downside: The plastic can dig in if you sit too long. Shrug it off. Beauty is pain, right?
