* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.

This bra is super sexy. It's as supportive as it needs to be. Not going running in it anytime soon, but it makes the girls look great. I love it, and so does he.

The Sieve collection in Babe is absolutely beautiful, not to mention comfortable. I find these bras absolutely wonderful and have purchased in several colors now. I could wear just these every day.

I exchanged for a different color as the pink feels like candy to me, but I love the fit and the style.

The color is spot on. Subtle and a little smoky with a neutral undertone that matches everything. Buying another one.
