This is a fairly recent film I can’t find.  I think it was between 2000 and 2010.  The first interesting thing about it was that the lead actress was not some skinny and bones or perfect body type. She was a (normal) heavier-set girl. Lovely face and longer hair (i think blonde). She worked at a burger joint and her deadbeat dad worked there too. She meets a boy who is kind of different and in one scene, he takes her to a party where everyone is unusual and interesting. I think someone in that scene was wearing a trash bag as a dress or shirt. I had IFC at the time, and a few other movie channels but I can’t find this title anywhere. I consider this a movie like The Planters or something by Miranda July. Thanks for your help
