These are 2ml neoprene so not nearly the stretch of our regular swimsuit fabric. Neoprene is meant to fit quite tight and should be a bit of a struggle to get into in order to provide the warmth you are looking for. This size guide is just a guide, and if you have worn neoprene, you probably have a good idea how to fit yourself. We have the CHEEKY style that is higher on the hip and medium coverage across the bottom. And the FULL BUTT CUT style that has a good bit more coverage, but similar sizing.
If you have questions, call us @ 949-230-0550. Exchanges are easy if the sizing is off!
