Hide her shoes and jumper

Emma has been so focussed on her ruined skirt that her other discarded clothes have momentarily been forgotten about. Quickly moving back across the library you pick up her shoes and jumper sending them away into the either. It doesn't leave Emma very exposed, but it's definitely a start.

A few minutes later Emma reappears near you. "I'm sure I left them here." She mutters to herself, looking rather embarrassed and clearly liking for her clothes, with just five minutes till opening.
