Allow her to put them back on

You undo the restraints on the chair, and grab her clothes, placing the stack in front of Evellyn. The fact they're neatly folded feels like an additional slap in the face, one you delight in.

"There you go."

She seems a little taken aback you've actually acquiesced, and relatively quickly at that.

"Uhm.. T-thanks." She covers herself with one hand and reaches for the clothes with the other. She holds the bundle in front of her chest, before looking you in the eyes.

"Turn around."

You don't turn around.

Grumbling, she quickly gets herself dressed while you watch, unable to prevent exposing herself time after time.
