The bra

You smile to yourself as you watch Emma continue to work, her hands almost constantly playing with her skirt and vest. Of course you're also beginning to run out of things for her to take off without making her indecent.

"It's liberating dressed like that." You push into her mind slowly. "But you've still got your bra on. Under that vest no one else will know if you're wearing it or not."

Sure enough she doesn't take much prompting, and teaching up her vest she quickly unhooks her bra, sliding it out the edge of her vest, now in nothing but a skirt, vest and stockings.
