Looking at the size chart, I was a in between the L and XL, so following the website guidance I ordered the XL.
However, it was too large for me. It was extremely baggy in the belly area, had a huge pocket of air in my lower back and I had tons of extra material in general. The wrists and ankles were not a tight fit and allowed for air/water flow (although you can always fix that with diving straps). The way it fits me would totally defeat the purpose of wearing a wetsuit to keep me warm (see picture).
For reference, I have a curvy female body, which makes cloth fitting a challenge most of the time: I'm 5'6" ft, weight 146lb with 35" chest, 27" waist and 44" hips.
After receiving my wetsuit, I emailed customer support and they were super responsive, assisting me with the process of getting the right size for me. I only wished I had contacted them before ordering, it would have been much easier. I recommend you contact them before ordering, specially if you have questions or are in between sizes as I was.
Other than that the material looks high quality and feels nice. And I love the yellow color!
I will definitely be buying the rest of the equipment through this site in the future. Thank you!
