* 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.

This has been my go to bra for 4 years now. The other week I forgot it in a dressing room and lost it! So I immediately bought another one. Can't go without it. Comfortable and sexy

I live in a tropical area. These are very breathable and very comfortable. However, there must be gently hand washed in the sink and even with gentle hand washing, they do not last long they’re extremely delicate.
