Questions About what to wear to a kesha concert

What could I wear with grey ankle boots?

I am going to see Kesha in concert on Saturday. I live in WA and normally by now the weather sucks, so I bought black skinny jeans, grey ankle boots and a grey lightweight sparkly sweatshirt to wear. But now, its going to be about 80 degrees in Seattle! I will probably still wear the shirt because it only goes to my elbows and I want to wear the boots really bad! What could I wear with the ankle boots instead of skinny jeans?? Thanks for your help!
