I went to a surfing lesson and these were the suits we wore. I knew my size and I double checked the size chart and I am in between sizes on the size chart so I know I fit in the size up so going up a size if you are in between is probably a good idea. My chest was in the size up and my waist was in the size down and my weight in the size up so I went up and it is right on. I hope this helps. It is a really nice wetsuit.
I am pleased with my purchase. Arrived quickly and the suit fits well. I called and got help with sizing, I am typically a 6 in womens clothing which does not have anything to do with wetsuit sizing - lol. I ended up in a 8 in a wetsuit size. Was perfect.
My size was a bit too snug but once I returned & went up one size it felt great. Went out this past weekend and this was the first time I ever wore a wetsuit (especially on first day of the wetsuit wearing season) where I didn't feel like I was restricted. I've never worn a wetsuit that didn't feel like you were doing a resistance workout while paddling--but this baby delivered! Get a size bigger than you normally wear & you'll be pleased.
