I know how much it sucks to blindly order stuff like this, since i pretty much buy everything for snowboarding the same way. If this can help:
I had it tightened around the waist, so it went up a bit. With the stagger pants i wear it loose and comes down to half my butt or something like that, i think i sit on it when im on the lift, and you can see that the sleeves are pretty long.
I saw a guy once wearing that haakson guy's version (like from The B, so i think its last season) it was like 3 sizes larger, looked a lot like a hoodrat (which actually isnt so bad if youre short) but then again there are so many jackets other than the AK line which are much better suited for style.
