Try it in reverse: is there something you feel you wouldn't mind wearing?
Once you've established what you can wear google for a song Example:
Gypsys, Tramps & Thieves !!
However I have the easiest option by one of my favourite bands:
Green Gloves by The National. Gawd I love these blokes, I've seen them a few times and I'm kicking myself for not getting tickets to Latitude this weekend, they're playing tonight...
