* 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.

I generally do not like synthetic material on my skin, but after searching high and low for a comfortable bra to fit my small frame, I decided to give this one a try. In my 50 years of life, I have never found a bra like this. It fits well. It stays in place. For once, I am not rushing to take a bra off. This bra is amazing.
