Sizing is off on this new run

I have 3 of these I got last year all size large and they fit great and still fit great! I got a black one, the re-stock that just came out, the large was tight, not roomy like the others so I figured sizing was maybe off? I ordered the XL and its HUGE, swimming in it. So I'm not sure what's up. Its almost like the large was mis-labeled, like it was a medium but labeled large?

Set it and forget it

I have worn the S.E.A. Suit many times and I can say without hesitation that it was a good purchase, maybe even great. I bought the medium, I am 5'10, about oh, 140 pounds and I have a long torso meaning that one piece swimsuits and jumpsuits can be tricky. But the SS fits very well; I can raise my hands to grab something up high without feeling self-conscious. I wore it on a plane ride and didn't feel rumpled and frumpy when we disembarked and that's after sitting between my two little ones, eating, coloring, playing, etc for 4.5 hours. Overall, two thumbs up.

Loved it from the start

Perfect - like it was made for me. As soon as I put it on it felt like an old favourite. At least 5 compliments from (very stylish) strangers. The only issue I have is that it is on such high rotation!

So easy to wear

I have and love this in pitch black, so I about died when I saw the new hibiscus pink color and ordered it immediately. It's so fun! I can't wait to wear it. I'm 5'6 and 140lbs and wear a S.
