The letter 'i'

You couldn't even begin to think what your outfit could be just with the letter I on the card, so you head over to the changing room and see what looks to be some sort of red spandex outfit laying there. You spend a few minutes squeezing yourself into the suit and turn to see that you're a member of the Incredibles family! Not your first choice of outfit, but it'll do. You go to leave again but you feel a sharp stabbing pain in your stomach as all your muscles begin to ache. Your hips widen and your stomach becomes more toned. Breasts can be seen protruding from the suit and your hair grows down to shoulder length and turns a platinum blonde colour. Your boots gain a 3-inch heel as you conclude you've actually become Elastigirl!
