how cup size and band size work

“I’m a WHAT?!”

TweetHello Ladies, Often times during a fitting, I hear women exclaim “I’m a what?!” when I tell them the cup size portion of their measurement. “No, I can’t possibly be a (fill in the blank) cup!” Sound familiar? Part of this confusion arises from a long-standing misconception (propagated in part by the media) about how cup sizes relate to a woman’s boobs. The lovely and funny Sofia Vergara, for example, claims to wear a 34DD bra: So, women (and men) associate a DD cup with Sofia’s ample chest or Salma Hayek’s or Jessica Simpson’s or . . . and the list continues.  One perusal of websites claiming to know “celebrity bra sizes” reveals similar seemingly large cup sizes for celebrities with bigger-than-average chests (Christina Hendricks is a 38DDD?  Are you being serious?).  For what seems like forever, cup sizes have been regarded in this way: A’s are flat, B’s are small, C’s are average, D’s are big, DD’s are huge, and DDD’s are ridiculous. The truth is, however, that cup sizes mean absolutely nothing on their own.  But, why?  Cup sizes are only one half an old married couple, and it is their long-suffering partner, the band size, that gives the cup size any kind of significance.  The little known fact to finding the right size bra is that cup sizes vary widely from one band size to another, i.e., a D is not a D is not a D. Bras, like other fashion items, are built on the idea of scaling proportion, but the scale does not center on the cup—it’s the band that’s the star here.  The band of the bra is designed to represent your torso girth with everything from the width of the cups to the placement of the straps to the length of the wings
