"I moved here over the summer"

"I moved here over the summer" Cassandra said, making up the lie quickly in order to explain her sudden appearance at Hogwarts.

"I guess you're one of the few" Draco observed. Hogwarts didn't have many transfers from other schools.

"Yeah, I guess I am" Cassandra brushed off with an awkward smile, as they entered Madam Malkin's.

As they were measured by the shop's assistants, Malfoy started talking about his family and Slytherin House, Cassandra was struck by a memory. This was how She had first met Malfoy as Harry, and yet here she was, casually making small talk with her enemy in the same spot. Somehow she managed to suppress those feelings and started asking questions about Hogwarts and the Various Houses, feigning being unaware.

"This young lad's robes need hemming" Madam Malkin instructed the assistants while looking over the pair, "And your robes are a fright, young lady, where did you get these?" She asked Cassandra, gesturing to Cassandra's ill-fitting clothes. Cassandra was trying to come up with an answer when Madam Malkin remarked "Never mind, I don't want to know. Come with me, this will need my personal attention."

Malkin lead Cassandra into a private fitting room. "I just moved here, can you help me with the British styles?" Cassandra explained.

"Very well, I like a good challenge." Malkin responded, summoning a few robes off a rack outside. "These will need to be altered, but I think will look excellent on you."

After 30 minutes of trying, altering, and fitting, Madam Malkin found robes that fit Cassandra's new body exceptionally well. "I normally don't deliver immediately, but you need these now." Malkin explained as she applied the Slytherin markings and handed the robes to an extremely grateful Cassandra. She now had clothes that fit, putting them on, and putting her hair up using a spell She barely remembered, She walked back.

"Wow." Malfoy said, stunned. "You're beautiful." ( Cassandra blushed at such praise from an old enemy.)

They walked out back into Diagon Alley's crowded streets.
