Sadly, you can't go back in time to start planning your Halloween costume earlier. The next best thing? Pay tribute to Hollywood's favorite time-travelers with a "Back to the Future"-inspired last-minute couple's costume. For Marty's outfit, go with a pair of cuffed jeans, a plaid button-up, white sneakers, sunglasses, and an orange puffer vest — watch recommended. For Doc Brown, a lab coat, a button-up with a colorful pattern, and a pair of khakis should do it. If you really want to sell the look, try adding on a pair of goggles and a white wig.
