We found Vivi's Indian tea party dress for ten bucks at Kinder Klozet, a local children's consignment shop. The owner Lyn's good friend is from India and her father sends his granddaughter TEN fancy Indian dresses every Christmas. The tags were still on this one.
We were going to have her dress as Alice in Wonderland and I had a special blue full tutu skirt made for the occasion, as well as an apron just like Alice's, but Vivi took a dislike to the expanse of the skirt. (The outfit probably cost $100 in total and she preferred the $10 one -- take note, other mothers with Ideas.) I'll try to get a photo of her in it later, when she's up to it. She even has a pair of white gloves to go with it.
