Actually, that's probably the waitress skirt. In previews, Amy used to have a waitress skirt that she sort of flipped around and it was the pink sparkly skirt, but she broke it somehow during the show, so until they got a new skirt made, Amy had to keep the regular waitress skirt on during Right In Front Of Your Eyes. I remember reading an interview with Cara where she said she had to wear Amy's costumes when she first went on for Amy because hers weren't ready or something, so I'd assume that's what's going on there.00
