Sparkle Ferret

My costume was a black shirt with the Batman logo, a cheap black cape, black pants, and a Batman knitted cap.

The Garrett ferret notifies a passing ferret, "Um, you still have some glitter from your Halloween costume-" which the sparkly ferret bursts, "IT WON'T COME OUT!"
I had the same costume for Halloween 2018! Minus the cap. Now I wear the shirt about once a month as a regular shirt.
