She gives you the schoolgirl outfit.

"Here, you can wear the schoolgirl outfit." She hands it to you and you shrug and start putting it on. "I'll wear the security guard uniform. I'll go change outside." She leaves the room. You find the clothes easy to put on. The panties are a bit tight, but silky smooth. You put on the bra next, and see she has it stuffed with gel inserts so it doesn't look silly. They are quite large actually, and you see the tag on the bra is 44FF. You wonder if she would have even bothered wearing the underwear herself since you doubt she would fit in it. In the mirror, you don't look half bad. Your ass looks nice in the silky white panties, and the large stuffed bra jiggles realistically. The bulge of your junk in the front of the panties is the only giveaway. You slide on the hose next, and then put on a shirt that barely fits over your fake chest. The bottom of the shirt rests just below the bottom of the bra, leaving your midsection bare. The jacket barely fits over your fake bust, but you zip it to the bottom of your rack. You pull up the skirt and put on the long blonde wig and you are done.

"I'm ready," you call out to her. You wonder what she has planned.
