I love my OnePiece, ultimately I certainly have taken him in a different size and different color. In the description it says that one should probably. a number chosen to be smaller than normal because it fails big, which is not true in my eyes. Then he sits namely close to Po and legs and crotch he hangs baggy 10cm by, and that does not fit together. I usually wear S or 36, pants size 27 and had decided for XS - which went from mentioned reasons and the S was the right choice. For color: in the photo looks the navy very nice, also in contrast to the white zippers. In real, I found that it somehow seemed as when new, like having a blue sweater since 10years, which is then washed out a little. Does not look cool, but old and pale. From the comfort you need to lose a lot of words I do not believe :-)
