For reference I’m 5’4, 160lbs and a 38in bust, 31in underbust and I got a size large. The color is beautiful and the fabric feels really nice on the skin. My main worry was the support/ cup size and both are great! My boobs actually fit in the cups, and I don’t feel like they’re spilling out/ look saggy! With the halter neck, this suit is easily adjusted to accommodate for torso length or bust size. I would say I have an “average” bottom for my height and build, and it didn’t ride up or feel uncomfortable. And it ties at the front, allowing you to cinch it to fit what you prefer.
