The jeans were a part of Kristen’s look that we’re 100 per cent sure aren’t Robert’s. She went for a super skinny jean to make her super-sized stolen t-shirt look less overwhelming on her tiny frame. We’re sure almost every girl owns a pair of skinny jeans, so toss on yours and you’re ready to go. (This may be the most comfortable costume ever.)
