Victoria Secret Runs Small?

I'm thinking they have a marketing play to get you to buy their product - tell you you're bigger!  I have never had a VS bra but after augmentation since it's their bra sale I thought I'd give it a try.  The measurement came up 32DD.  The other bras I had tried at the mall in the department stores fit just fine at a C.  I heard one girl come in saying she wears a 34A and the lady said , here, try this one on because I think you're a 32C.  What A cup wouldn't love to hear they are a C without putting out the dough like I did to actually get there :)  Just about everyone was at least one cup size bigger from what I could hear.
