What to wear: Obviously there are tons of options to choose from with this movie, but Rihanna's is the most relaxed. You'll just need an oversized green coat, baggy jeans with rips in them, a t-shirt in camo print or an XL striped jumper, and a patterned scarf to put in your hair. She also wears brown Timberland boots in the movie, for what it's worth.
