Bikini help?

It’s spring break and I’m finally in a relationship where I’m comfortable enough to go out to the beach/pool with him. Sadly, I’m a DD and can never (ever) find a bikini top that will fit and cover me well. I know I could use a one piece, but it tans horribly and I don’t want the weird tan. Any suggestions other than VS as into where I can buy tops for top heavy girls?
