Non-Wire Bra Sizing
Your underbust: | A | B | C | D | DD | DDD | G | |
---|---|---|---|---|---|---|---|---|
24-26" | 30 | 0 | 0 | 0 | 1 | 1* | 1+ | |
26-28" | 32 | 0 | 0 | 1 | 2 | 2* | 1+ | 1+ |
28-30" | 34 | 1 | 1 | 2 | 2 | 3* | 2+ | 2+ |

* 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.

While this bra is fine, the cost for the material and quality is not worth the expense. This is a $30 bra all day long.
