Still looking at your newly developed small breasts in surprise, you look what else is there...from an underwear drawer, you take a piece of rather bland looking underwear that looks like it'd fit a 12 year old. Deciding it can't get any stranger anyway, you carefully put your feet through the holes and pull it on with much difficulty, chafing your legs a bit on the way up. You now have way too small female underwear pulled on completely tight around your groin, and because it's rather uncomfortable you decide to take them off again...then, suddenly, you watch the lump in the front quickly become smaller, smaller, smaller...until the front is completely smooth. In shock you stretch the fabric a bit to look, and what you see it an almost hairless surface with a small line running across the center that looks like a gap...and in fact, it is: your new bald vagina. You let out a scream in error which is almost ear-deafeningly high-pitched as the underwear continues to work its magic and you quickly lose size, instantly shrinking well over a foot. Your muscle mass completely disappears along with it, leaving you with the posture and body of a rather fine-built 12 year old. Aside from that, you've noticed that your hair now reaches your chest, neatly combed backwards into a flowing wave of hair. Right, so now you're a 12 year old in her underwear...you decide you had best find some clothes to wear, as it's rather cold in here.
