I just went through the same thing!!! I'd been wearing the same size for years and thought it was all good, even though the wires in my bras kept popping out, as well as other things

. My girlfriend told me to get fitted, because I probably grew, and I said no, I've been wearing the same size for years. WELL, we went to the mall one day, and I got fitted alright. I told the sales lady what I usually wear, and she measured me and was like "Ummm, no." I said well whisper in my ear what my size is because I didn't want my friend to hear.

. Needless to say I had to go out and buy all new bras, lol.
