A "dress"

Your jaw almost drops when Melanie walks into the room. She picked a dress, but it's a dress designed for a girl less than half her age.

It's made as a long dress for a dance or other formal affair. It's a deep red color, with a fancy lacy pattern. It has no sleeves, with elastic straps going over the shoulders. For the intended wearer, this dress would have easily reached the ankles... But on Melanie, it barely reaches past her ass, and only because she's pulling it down as she walks. The waistband of the dress is fitted around her chest, directly underneath her breasts, lifting them up quite nicely. They bulge out of the material that's supposed to cover an entire torso, barely-contained.

"Honey, I hate to disappoint you, but none of these clothes fit me."

You shake your head. "No, they're all perfect. It's just the new style--You can stop pulling that down."

"Oh, of course! You're right." She lets go of the hem of her dress, and it immediately springs up to reveal her ass and pussy. You're pleased to see that she's wearing a pair of Hello Kitty panties that just barely fit. You were a bit more generous with some of the underwear: it's fun watching her walk around in tiny clothes, but you're not interested in torturing her.

She sits on the edge of your bed. "So why did you call me in, sweetheart?"
