A low back bra drops the band down toward your waist, or does away with it, so it hides under open-back dresses and tops. Pick by how low the back goes: a dropped-band bra for mid-back openings, a convertible bra with a low-back converter or a longline for low backs, and an adhesive bra when the back is open to the waist.
Match the bra to the back
| Back opening | Best option |
|---|---|
| Upper back (just below shoulder blades) | Racerback, halter or strap clips |
| Mid back | Low back bra with a dropped band |
| Low back (near the waist) | Convertible bra with low-back converter, or low-back longline |
| Open to the waist | Adhesive bra or built-in support |
| Open back with straps | Clear-back or multiway bra |
Types of low back bra
- Dropped-band bras: the band wraps around your waist instead of your back.
- Low back converters: an extension that pulls a regular bra’s band lower.
- Multiway and convertible bras: straps that cross, halter or go clear.
- Clear-back bras: a transparent band and straps.
- Adhesive bras: no band at all. See our stick-on bras guide.
How we chose these
We matched each product’s listed construction (cup shape, band, straps, wires and fabric) to what helps with open-back outfits, and favored long-running Amazon listings with a large number of buyer reviews and a wide size range. We haven’t tested these bras ourselves, so use the fit checks in this guide when yours arrives, and keep the tags on until you’re sure. How we earn from links.

How to fit a low back bra
- Try it with the outfit. The whole point is that it hides; check in a mirror from the side and back.
- Band firm at the waist: a dropped band has to grip without rolling.
- Cups secure: with less band, the cups need to fit well to stay put.
- Move: sit, reach and dance a little.
Fuller bust?
The less band a bra has, the less support it gives. From DD up, see backless bras for large breasts, consider a dress with built-in cups, or read our guide to the bra for a backless dress for alternatives.
