Before you say anything, I do know the pic is crap. I also know the sleeves are too long (for now) and that the jacket is wrinkled.
The sleeves and wrinkles are how they are because I just got it and I'm trying it on.
I'm exceptionally new to wearing things like this. A year ago I wore ill-fitting jeans paired with overlarge sweaters/tshirts.
I've been reading the forum quite a lot though and am learning.
