Drop Dead Fred:
I thought of this and I think you'll like it.
1. Leprechaun costume
What to do:
2. Orange wig (if you don't already have orange hair)
3. Yellow T-Shirt (any)
4. Clown shoes
Remove white satin vest with shamrock print from leprechaun costume. Spike orange wig or hair with hair gel.
Trim curve at bottom (optional).
Put on your new costume
Thanks to Llyse for this new idea!
