Plus-Size Bra FAQs
What makes a bra plus-size?+
Plus-size bras generally refer to band sizes 38 and above, or cup sizes D and larger. They feature structural additions like wider bands (3-4 hooks), supportive wings, and padded straps to offer maximum weight distribution.
Why does the plus-size calculator offer a 'Firm Support Size'?+
Softer tissue on the ribcage allows the underband to slide easily. Going down one band size and up one cup size (sister sizing: e.g., 40D to 38DD) compresses the tissue slightly, keeping the band locked in place so the straps don't dig in.
How do I measure my underbust if my ribs have soft tissue?+
Wrap the measuring tape around your ribcage snugly, compressing any soft tissue. Sizing is based on bone-level support, so the tape should feel firm but not painful.
What is the best type of bra for a plus-size bust?+
For daily wear, structured underwired bras with side-slings and wide straps offer the best lift and separation. For lounge days, supportive wireless bralettes are highly comfortable.
