I need some dress ideas for a farewell party, help?

I'm attending my high school's farewell party next month. I just bought a cropped black leather jacket with strong shoulders with sleeves about elbow-length, and I'm planning to wear a pair of peep-toe ankle boots, I'm doing a messy wavy Ke$ha-inspired hairstyle. But... I still don't have any idea for the dress. It has to be a dress, and a green one. Do you got any idea for the dress I could wear that goes with the shoes and the jacket? I'd really appreciate that. Thank you! :)
