Give her stuff back

You fling her clothes back to her, one by one, watching eagerly as she has to catch each garment and expose herself again and again. Then you plop down on the nearby couch and play the spectator to the sport of trying to get dressed as quickly as possible. She's got her back turned towards you so you can't get another eyefull, but you at least get to look at her ass and bare back.

She puts her bra and thong back on, and doesn't even bother with her stockings and garterbelt before slipping her dress back over her head. She turns back around. You can see she's clearly still incredibly embarrassed as she tightly winds an arm around herself, covering herself despite being clothed again.

"The staff"

"Ah, yes, true enough. Catch." You leisurely throw it back to her.

She catches it, and quickly flees towards the window after the other elves, clutching her staff in one hand, and her stockings and garter in the other. You watch from a distance as the elves flee into the night - two of them naked, and a third equally embarrassed. Another job well done, if you do say so yourself.
