We've got a little over a week until Halloween. Maybe you're not really into the whole dressing up thing. Or maybe you're considering it, but haven't decided yet. Perhaps you're about to give in to that friend that's begging you to come to the party or the bar or wherever they want to go ("but you've got to have a costume!"). In any case, here you are—without something to wear. The good news is that you can dress up like some iconic characters, mostly from pieces you already own. Got some aviators and bomber jacket? Boom, you're Maverick from Top Gun. Do you own a denim shirt and a bottle opener? You can be Cool Hand Luke. Besides, there will be plenty of Trumps, Ken Bones and Jared Leto Jokers already.
