Halloween // Cassette Tape halloween costume accessories?

I'm going to see an 80s cover band at a concert later this month. They're encouraging people to dress up because there's going to be an 80s costume contest.

I bought this Cassette Tape costume and I'd really love some help choosing some accessories because it's just the cassette tape. It's not the black pants/shirt.

Should I go 80s exercise? maybe a Sweat Band or something?

Should I go in the style of Bret Michaels, Van Halen or Steel Panther?

Give me some ideas please, links are appreciated. I'll consider everything!

Thank you <3
