Halloween // Pls help me find a costume

Hi! On saturday I have a birthday party, i have to go with a costume from a movie or tv series and the most silly or creative is getting a price. I don't know which costume can i make.

I have some things than could help to think for ideas:

• jeans overall
• yellow umbrella
• yellow raincoat
• black boots
• ups uniform t-shirt
• tons of stripped t-shirts

and i'm kinda crafty, so i could make some props, but nothing to elaborate.

pls help me!
