Mrs. Anderson's outfit.

"I'll try on yours, Mrs. Anderson," you say.

"Excellent choice, Parker," Mrs. Anderson replies and gives a smug smile to Belinda who makes a face at her.

You're a little bashful as they clearly expect you to change right in front of them. You strip off and put on the panties and bra Mrs. Anderson selected. Then Belinda helps you into the dress and you put on the heels.

Mrs. Anderson does your makeup quickly and gets you her jewelry to put on. When she's all done, she has you look in the mirror and you find that you look quite sexy and elegant in your little black dress. You are, perhaps, a bit overdressed for school, but neither of them seem too worried about that and they'd both know better than you would.
