Go get professionally fitted at a high end place like Neimans or Nordstrom (my favorites). Dillards usually has good fitting specialists as well.
Remember You get what you pay for!!!
My favorite is Wacoal. I got them at Neimans but they are sold at Macy's, Dillards and other department stores.
I do not like any padding, I like sheer cups, no lines and underwire but Wacoal has a wide variety of styles. I am very petite 5'5", 116# size 2 and I have natural 34DD's. I like a functional bra. Fortunately through my genetics, my female relatives are naturally large breasted, very dense, firm and perky... I intend to keep it that way :)
Victoria's Secret is not bad. My 15 yr old daughter does like a little padding and she loves the Victoria's Secret bras. She is a 32B.
Good luck!
