My usual size is M but ordered a L and it fit perfect. I’m in love with this bathing suit. 5’4 tall 160LBS Waste size 39in

Bought my true size, small, as with all one piece bikinis I buy from fashion nova. The top on this one though it does run a little tight, so I would size up if you have really big breasts. I have natural 32DDD’s and it fits just a little right, but nothing uncomfortable. The bottoms fits true to size. Buy your true size if you’re not top heavy. Great quality as well!
