those sleeves are fine, its rick, and they always look like that unless you got the lankiest of arms. The ribbed cuffs are on some jackets not most, probably more on newest ones. Shit you should see the denim jackets, the sleeve lengths go past your hands fingers.
Meh, I'm usually onboard with the criticisms of KJ's sleeves, but this seems like nitpicking just because it's KJ and we've become conditioned (AS A COMMUNITY!) to instantly look at the sleeves and prepare our criticism when we see a KJ fit.
