I can't help but notice the overall exotic tone of the movie. With these costumes, it puts enough bizarre new age feeling in it.
In above shot, Marcel's outfit is like a lama monk's robe.
Here, each couple wear similar costume with different colors during their therapy sessions. In the end of the movie, each couple will be awarded with different animal sculptures, which reflects their own animal nature. Sounds like Kung Fu panda, isn't it? Could you guess which animals they would become?
