I gotta vote for the one on the left, too. The one on the right, with those shiny puffy gold sleeves...what were they thinking?...doesn't even look like Cinderella.
I would choose the cheaper. I bought it for my DD who's almost 2. She wore it to eat breakfast at CRT on June 22nd. Adorable pictures. It must have been comfortable-she didn't want to take it off. I personally wouldn't spend the extra. She'll outgrow it. The cheaper is good quality. I love it!
