Then there was the zebra pair. The fabric looked like it would glow great in UV.
It did, but I used these for an outdoors costume party, so never came near a blacklight. It was a fun costume though!
The rest of the costume was a zebra headpiece with a large mane extending a foot above my head and all the way down my back. Oh yeah, and a tail. My friend Carlos painted my face with striped motif, rendering me unrecognizable.
