You can find this when Nick is in his boss's office during the beginning of the movie, and he thinks he is getting a promotion. After his boss tells his assistant to bring him a new tie, when he turns around and to sit down, you can see that his tie is tan, with no designs on it. Then, when T shows a close-up of his face, you can see a design on his tie. Then he changes into a lavender tie. So did he change his ties twice????
