Hi, I'm 18 soon 19 and I have a big bust, i think i am a 36 c or d, not really know cause i have always were sport bra cause they give me more support, but now i whant to start using regular bras but y dont know which one is going to fit and and get the twins in place.

i know what you mean. I wear a 34 D and taking a trip to go bra shopping is always a nightmare. If you're not sure of your size i would definitely recommend going to Macy's pr a similar store and get fitted. They have professionals there who know what to look for and how to solve your problem. It may be a little awkward, but you have to remember that they do this stuff all the time. And it is well worth it!
