"Er... alright. Twilly, please lead me," she stammered.  The house elf led her down the hall to the same bathroom she'd used yesterday (was it yesterday?) and turned on the shower for her, then left her alone.   When she emerged twenty minutes later, showered and dressed in the slinky black garment she'd found waiting for her, she found the elf waiting in the hall. Twilly led her back to her room and a tray of food appeared, with juice and tea.  She ate and drank ravenously while the elf stayed by her side.
