H&M celebrates its 2018 Spring Collection with an all-female dance party. When Elizabeth Olsen dances with her male partner, she can't hide her boredom. A woman in red taps in to dance with her as Young MC's "Know How" begins to play. The two dance passionately to the upbeat track as women on the street join in. A clap silences the room before Winona Ryder reveals herself. She clasps Elizabeth's hand and moves in close, ready to start their tango.
