* 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.

While this bra is fine, the cost for the material and quality is not worth the expense. This is a $30 bra all day long.

The overall look and comfort is good. The band folds a lot and i wish straps were a little thicker. I will try different styles though.

I recently switched from underwire to no wire; the difference is palpable. This is the most comfortable bra I have ever worn, yet super supportive. I'm not in a rush to rip it off at the end of the day!
