He was a WHAT?

A Port-a-Potty. Specifically a Honey Bucket.

(notice the flies and TP roll? A nice touch, I think.)

And this guy was an assassin.

(Yes, I can appreciate a cheap costume if used with enthusiasm.)

A clock

(10 bonus points for originality, am I right? She was looking around the house, saw a clock and said "I want to be a clock for Halloween." That's how the Halloween magic happens. Eyeliner numbers, the hands are game spinners we stuck on with goop, and we stole the pendulum from the clock that inspired it all. )

and

A Purple Toothfairy

(bought the fabric, sewed the dress, made the tutu)

(watched turn-a-headband-into-a-tiara tutorial on YouTube and made one)

(threaded the "teeth and pliers" necklace and added googlie eyes to a felt tooth)

(and JO added the bag of cash, also a nice touch.)

Costumes are fun. Hope your Halloween was Happy!
