Hm... I think the stuff I have is more "teacher" than "schoolgirl" (though the latter would be more fitting) and I have actually been mistaken for one of the teachers a couple of times, haha. The outfit: platforms, black tights, black pencil skirt and tight pink/nude button up shirt (with my nicest underwear underneath.) Either that or perhaps my blue shirt and little red heels- they're quite sexy ^^
If I was simply imagining an outfit out of any clothes, I'd say lacy black thong and matching push-up bra, with suspenders, garter belt and black stockings. On top of that, a half-unbuttoned white shirt and jumper over a short black tube skirt, with strappy black heels. Oh, and some sexy glasses, of course
