What to wear: Similar to the idea for Mrs. Potts, you're going to want to dress in all white, with hints of pale blue and gold mixed in. Maybe a blue or gold tutu? Or some gold lipstick? At the very least, though, you have to work the character's beloved chip into the costume (a hat or crown with a chip in it will work!).
How to act: Adorable, social, and prone to blowing bubbles in your Halloween punch.
