You can do it yourself. But what would be best is to go into a department store like Macy's, Dillard's, JC Penny especially, Victorias Secret ( you don't need to buy VS bra if it's not in your budget) and ask if you can get fitted for a bra. It's simple and also make sure that when you wear a bra that you wear it properly with no breasts exposed or smothered by the cup size and that the band isn't too small. When you hook the bra make sure that the the bra is hooked in the middle and it's not too tight, adjust the straps also for a perfect fit.
