Eva Chen's Must Haves: From H&M Tees to a $12 Sleeping Mask

In line with her classic style, Chen believes that a white T-shirt like this H&M Cotton T-Shirt ($8) is an absolute wardrobe must have. You can dress it up or down for any occasion, from the office to an impromptu night out. "I think that the perfect white T-shirt takes you everywhere. You can wear it with jeans and heels, put on some necklaces, put on a red lipstick, which I don't know how to do by myself, but you know what I mean," Chen says.
