It's the 34 for my regular 34. It's just a bit tight, but I don't think a size up would work. And I absolutely love it.
In terms of color: the colours are warm. The undertone is a warm beige, and the rosewood line sets that tone. The green is a warm khaki, the light blue is cold but freshens it up. I think this is such a nice piece, because it'll work with all these colours, as well as black and white, and you can wear it both casual and business chic I think.
