The material of the dress feels smooth against your skin, almost as if it is making your skin softer as it touches you. You are surprised to find that the dress fits, not realizing that it has already caused your body to shrink. You develop feminine curves and dress as the clothes change your body to fit perfectly.
As you put on the jewelry, you feel long hair flow from your scalp as your face becomes that of a beautiful woman in makeup. Your arms and legs become smooth and hairless as your nails become painted and your shoes extend into heels.
Your changes complete as your manhood disappears, and you find yourself alone in the strange room wearing the clothes you found there that now look stunning on you.
