The calculators are a good starting point anyway. The first time I used one, I decided I was a 38 band, but I eventually found I fit a 36 best.
Clothes were the same way. I first calculated I was a 14-16, eventually found I was an 8-10. The best thing is to try one on before you buy. If you must buy online, either buy from someone with a return policy (unlikely w/bras) or buy a low priced on on special.
Speaking of Vicky's Secrets, they're generally good about helping TG people in their stores. Their people can probably tell you your size just from looking at you.
