What to wear: A white long-sleeved shirt, white leggings, and a gold or purple tutu (go for purple if you want to channel the OG Mrs. Potts). Add in a frilly purple or gold hat to represent the top of the teapot, and clip some pastel flowers in your hair as a nod to those intricate designs (and maybe bring a little chipped teacup with you).
How to act: Warm and nurturing. Wander around the party asking everyone if they could use a cup of tea.
