Does anyone know the name of the song and the band I'm talking about?

I've seen this music video a couple times in the past week, I really like the song, but I'm not sure what it's called or who it's by. The video is set in a sort of seventies/eighties feel club, and there's this girl in the video with a boy hair cut and she's wearing a t-shirt as a dress. I think she's looking for this boy who walks into the club or bar, I'm not sure, with two of his friends, then she ignores him when he tries to approach her and he walks out with his friends then the girl follows him and they walk away together.
