Tough Sizing

I found this swim top to be tough to get the right coverage. In a small I felt like I was spilling out, but in the medium I noticed some bulging near the side of the top. I opted for the small, but still don't know if I am comfortable in how revealing the cut it is. The band has plenty of room, so that isn't any concern. It works well with the high-waisted bottom for a retro look.
