Maybe this was just a case of me not being a good match for this bra.  I'm not plus-sized (at least, not anymore), but this bra came in my size and I liked the modest neckline.  I bought it in my usual size, a 36C.  I have found that sports bras tend to have pretty widely varying interpretations of cup sizes, so that I can fit anywhere from a B to a D, so a C is usually a safe bet.  When this bra arrived, it was like a bad joke.  The cups were HUGE (and yes, I did double check the label just to make sure I was sent the size I ordered).  The bra overall was a bit big.  The band size was right, but the straps were long and the whole chest area was just hilariously humungous.  I understand that this is a plus-size bra, but why would you make a bra in a "standard" size if it's meant for someone much bigger?  It was just a terrible fit, and I sent it right back.
