Wait a sec...maybe there is no difference then. I haven't copped anything in d.blue this year, cuz everyone mentioned that they fit differently than the other cw's. #1 complaint I've read about them is that the length is significantly shorter. If that's the only issue you've had with Zumiez, then it's definitely not them. You purchase the same exact tee that you woulda got from Diamond directly.
No, because I compared the Diamond Blue shirt size with my other Diamond shirts in various colors (not washed). I've already read stuff about how Diamond Blue and Black run smaller than other colors. The Diamond Blue shirt was as long as any of my other shirts. Another thing was the hem tag. Diamond has two different types of hem tags that I have only experienced. One is wider with a smaller font, and one is shorter with a bigger font. All the cw of the Diamond LIFE shirt came with a shorter, bigger font hem tag, while the one I bought at Zumiez was wider, smaller font hem tag. I did some serious research before coming to a conclusion.
