Username ideas for Instagram?

[Cassidy]

Okay, my name is Cassidy and my middle name is Lynn. I sometimes abbreviate by name to Cassi, and use something like cassilynn as my username. But that's taken, and I want something more clever.
I'm an old soul, so I really like vintage/old fashioned sounding things. Almost kind of romantic like? My favorite show is American Horror Story, my favorite bands are Fleetwood Mac & The Rolling Stones. I like most late 60's- late 80's music. My favorite movie is the Goonies & I love The Notebook and the Breakfast Club and I really like those 80's high school movies. So now you know a little about me lol, any username ideas?
