You slowly don the blouse and skirt, trembling a little at the sensation of the fabric on your soft skin. Without panties underneath, you feel the open air on your privates and blush. You can't believe you're about to do this.
You open the stall door, leaving your things behind. You patter across the store in your bare feet and find the attendant from earlier tidying up a rack of collars and bracelets. You notice that you're at eye level with her now, where before you thought of her as "petite." You realize what that says about you now.
At the sight of you, she turns and smiles pleasantly. "Oh, you look so nice in that uniform! How do you feel? Do you like it?"
You blush again at being treated like a girl...practically like a child. But something about that intrigues you. Teases you.
"I'm not sure if I like it...," you say in your new female voice. You're still not used to it, but again something about it sounds good. "This whole being a girl thing is really strange. Magic costumes and everything...I would have appreciated it if you'd warned me."
"I did. I tell all the new customers. Maybe you just didn't understand when I said your body would fit the costume you chose. I'm sorry I wasn't more precise."
"It's okay," you say, feeling a little sorry you spoke so accusingly. "I can change back, right?"
"You can if you have your old clothes. I can show you how."
"Not yet," you say before you think. "That is, I...uh..." How do you tell her you're not actually ready to become a guy again?
"I know," the lady says. "I had a hard time adjusting when I tried on my first couple of boys' costumes." She lowers her voice just a tad. "But it's fun, isn't it?" She giggles like she just said something naughty.
You look down at your body, seeing your unsupported breasts pushing out the front of the blouse. They're a little uncomfortable, but you're already coming around to the idea of having them. The air on your bare thighs under your skirt feels cool and oddly stimulating.
The woman notices your indecision. "Are you interested in the purchase? Or would you like to browse some more? If you need any assistance, I'm glad to help."
