* 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 love the look and feel of the bra on me, especially during summer months. I do need to put in additional padding to avoid showing nipples when wearing more huggy shirts though.
