When Willow was two years old, I bought her an expensive Halloween Costume. It was a little too big for her that year. It fit her perfectly for the next year, but after that year I retired it, as the feet were getting worn down on the bottom.
It was retired into her dress up clothes.
Every so often--in fact, just last week--she becomes a KANGAROO!
It always amazes me that it still fits (just barely).
