* 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.

Customers have told us this bra is super comfortable and stylish! The mesh design keeps things breezy, while the fit strikes that perfect balance between cute and supportive. Many reviews mention buying multiple colors because they love it so much. While most find it fits like a dream, some note the straps run thin and a few wished for more support. Folks especially dig how versatile it is under different outfits and how it works great for warm weather. It's become quite the fan favorite for everyday wear!

i could have ordered a 4, I think, instead of the 4+, but since this material is not stretchy, I think i probably made the right decision. I love the shape that this gives me - supported but without the uni-boob that most of the tubey no-wire bras I have used offer.
