I saw this strawberry costume in person at Gymboree, and it was really cute! I'm thinking about getting it for Olive since it's on sale and I'm sure I could find a 20% off coupon too.

Our family costume is something only residents of Park Slope would get... I like to do original kinda obscure costumes.

Anyway Olive needs to be produce of some kind. Have you come across any fruit or veggie costumes?
