I may have to return this as well.  I ordered a L/XL.  Completely stretched out, this is 32" wide.  A few beads popped out.  I thought I would be able to just add a bra extender on the back, but this is way too small.  Cup size is probably A/B.  The tags are cut out, so you can't see what the original size was, but I'm sure it wasn't a 38 C/D as the description suggests.  It's pretty.  If I can't sell it to someone else in my dance troupe, I'll probably return it.
