This is a little scene from a human Toy Story/BLoSC AU fanfic where Star Command is having some kind of ceremony for it's crew.
Mira Nova, as being Jessie's best friend gives her a dress, which she knows it would catch the eyes of a certain someone.
The commissioner wanted some Star Wars and Star Trek outfits for Mira and Buzz to wear, which has been a bit challenging. (Never thought Buzz would make a good Price Charming in those clothes)
