Dude, I'm so pumped to wear my costume to the premiere. I thought about going in ROTJ Boba gear or maybe TFA Kylo, but I ultimately ended up falling on a little home-made costume. I didn't make all the parts so I can't really say I built it from scratch, but I bought the pieces individually, assembled, and weathered it myself.
Here me out:
Levi's 511 jeans because Luke wears Levi's in ANH
A grey hoodie just incase Luke turns out to be a grey force user
A polo with the Imperial insignia on it because bad guys are cool too
White ankle socks because BB-8 has white on him
Suede shoes because they are uh kind of sand colored like Jakku... yeah, like Jakku... where Rey is from
And no underwear because underwear doesn't exist in space. Right, George?
