You decide to wear her insanely beautiful prom dress, since most people had seen it before and because it was so unique that everyone would recognize you. Alexis hands you her biggest pair of panties, which are quite tight, but you want to go all the way with this. She also hands you one of her bras, along with a set of fake boobs to stuff it with. You go into the bath room and change into her lingerie while she changes into your clothes. When you come back out, she helps you with the dress. She also gives you the shoes she wore to with the dress, 3" red pumps. You just manage to stuff your feet into the shoes. As you look in the mirror, you see that the fake breasts do a very good job of imitating her very real breasts, but everything else just looks kind of weird. She then hands you a wig that perfectly matches her gorgeous blonde hair color and style in a way she would wear it to a party, which you promptly put on.
As you finish dressing, you stand up and realize how difficult it is to walk in pumps. Alexis, of course, has no problem with your black loafers. She also stuffs her hair into a skin-colored rubber cap, which she covers up with hair that matches yours. You head out to the party.
As you enter the door, you are greeted by Jamie, who is dressed in an amazingly sexy cheerleader outfit, which she tells you was bought from NBC. Apparently it was the outfit used by Hayden Panettiere in her cheerleaders scenes. She tells you that her birthday was just a week ago, and that she asked for this specifically to be her one present this year (her parents are head doctors at the two local hospitals, so they have plenty of money, even if they're house/cars don't say so). She tells you that both of your costumes are quite amazing, possibly the best she's seen all night.
As you begin to mingle with the other guests, your attention is turned to Jamie who is standing in the middle of the room. She announces that the final two guests just arrived (you and Alexis) and that the first activity of the night will now begin. After she finishes her announcement, she mutters something that sounds a lot like gibberish to you. Although it seems to be nonsense, the words still seem to be quite powerful. As soon as she finishes this, your vision blurs.
Once your vision returns to normal, you look to see none other than Hayden Panettiere standing in the middle of the room clad in her old sexy cheerleader uniform. Looking around, you see a familiar face looking at you. As you stare you realize that the face is yours. Suddenly, you realize several things: you have shrunk down to 5' 4", your costume is fitting like it was fitted specifically for you, even your shoes, and your 'fake' breasts are feeling quite a bit heavier than they used to.
As you look in a mirror, you gasp in Alexis' voice and immediately grab your (Alexis') hand and the two of you walk over to Hayden, who you assume is really Jamie, and demand an explanation. She tells you, in Hayden's amazingly seductive voice, that her parents hired a wizard who told her a spell to change people into what they dress as. Quite obviously, it worked.
What happens next?
