I went bra shopping this weekend at Victoria's Secret (they sent me a coupon AND a voucher for free panties. Who can resist free panties??), and the bra I purchased was not the size I thought I was. I tried on two different cup sizes and two different band sizes. Lets just say the band size did not need to be increased, but the cup size did. I think the old bra I was wearing was just so stretched out that it still worked for me.
