Do you sew? There can't be more than three yards of fabric in that costume. Pick up some pink gingham and Simplicity pattern #8851, and a few hours of quality time with your sewing machine later...you're set!
thank you thank you thank you for posting this!
i was also planning to be shortcake, or maybe alice in wonderland (yes, i am still undecided), but really don't have $60 to send on a costume from the store.
and i just signed up to post this LOL. i'm not the best at sewing, but i guess i'll have to try!
