She pondered the idea of a younger Snape studying in magical Amsterdam while he guided her to a room at the side of the entrance and handed her the dress. "She said you can use this room to change," he said. "I’ll be right here. Oh," he smirked, "and you won’t be needing any undergarments." She flushed and stepped into the small dressing room, taking off the clothes she had been wearing and slipping into the dress. It was shockingly short, and she felt exposed without undergarments, but she had to admit that it was flattering. She regarded her reflection in the mirror and smiled. Maybe it was her recent sexual experiences. Maybe it was the exhilaration of being in a muggle city where no one knew her, but she felt daring. She was excited at the idea of Snape taking her to a club... perhaps even taking her in the club... she flushed and shivered. She was nervous, but aroused... She took one more look at her reflection and then frowned at her shoes. Checking to make sure that there were no gaps in the bottoms of the wall that anyone could see through, she pointed her wand and transfigured them into strappy black stiletto high heels. She’d still be shorter than him, but they elongated her legs and made the outfit stunning. She added cushioning and stabilising charms to be sure she wouldn’t go tumbling when trying to walk in them.
