My friends and I did it last September. We all went Mary Poppins, LOL. We did Dapper Day the day before so it was a lot of dressing up that weekend. We planned to do it again in Feb. but 2 of us were unable to make it. I had a cool outfit all ready to go--Haunted Mansion inspired--but had to have surgery so I'm hoping to use it in an upcoming trip.
My friends and I have also discussed going as teacups. We had the idea and then we saw a picture of another group, maybe in WDW, wearing that very thing!

A little disappointing, but it was awesome. Each person has a different color and the skirt is the teacup with a design on it.
