I always make my own costumes...we've worn them to school for "Spirit Week" (Halloween happens to be in the week before homecoming) since 6th grade.
So these are what I've been from then to now.
6th- Pegasus
7th- Flamingo (Sewed those damn feathers onto the leotard for a week...)
8th- Olympic Torch (...don't ask)
9th- Cleopatra
10th- A little french girl
11th- yet to be decided...I'm thinkin BRAK
