Mitt Romney and Barack Obama– The presidential candidates make this one easy for those last-minute Halloween costume people. At many of Romney's campaign stops he wears jeans, a brown belt, loafers and a white shirt (occasionally with a blazer). Make sure you don’t forget the greying sideburns and coiffed black hair, one of Romney's more defining physical characteristics. President Obama also tends to wear jeans on his campaign stops, frequently with a white button down shirt and loafers. If you're going to dress as Obama, get something to make sure others know, such as one of those "O" bumber stickers.
