* 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.

On me, not nearly as flattering or as supportive as the Sieve Bra Top. Too much coverage on the chest,, but thin straps that cut in.
