Looking to sell my new street jacket. Apparently I'm retarded because I picked one size too small when I ordered this thing.

It's US 38 / EUR 48, which translates into a small.

It's only been tried on once, and is still in the original Alpinestars plastic packaging, has the tags, everything. These jackets retail for $500 - I'd like to get at least $400 back out of it so I can order another one.
