* 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 have large breasts and a small frame so finding something supportive AND cute can be hard. I was pleasantly surprised that this bra fit me and seems comfortable. I purchased for relaxing and casual days, but it’s so supportive I’m considering wearing to work under my scrubs.
