Breast part is very small

I love this bathing suit but it is slightly loose on me. I could've went to an xlarge instead of buying a 1x. It still fits nicely on me so I'm gonna keep it. But it's definitely slightly big in the breast area and i have room in the bottoms as well. So if your on the smaller side in breast cups u may want to size down for a more fitted look. I am 215lbs and 5 foot tall. I wear about a 34D in cup size for reference.
