Isla was somewhat surprised at Curtis' greeting to the group they'd formed. Her first and only encounter with him, other than this one, had been just after the feast when he and the Head Boy had gotten into an argument in the Slytherin common room. Since then, the first year's impression of Curtis had been that he wasn't very friendly and wasn't interested in making friends at all. Maybe she'd been wrong about him, though. She smiled at him before turning her attention back to the professor.

She raised her eyebrows at the professor's words. Were they going to have a Halloween party or something? That'd be kind of cool! And they going to make their own costumes? If so, it sounded fun, but she didn't see how this had anything to do with Transfiguration. Then again, there was that mysterious rail the professor kept looking at. The first year grabbed a piece of parchment and a few supplies to design her costume, even though she didn't have anything in mind. Hmm... She could really do something from the muggle or magical world, although some people here might not have any idea what she was dressing up as if she chose a muggle outfit.

In the end, she decided on a fairy. Before she started drawing, she got a good mental picture of what the fairy would look like, and then she jotted down a few notes.

Name: Isla Bellchant
Costume: Fairy

Hair: In a bun like a ballet dancer (possible silver, shiny butterfly clip)
Clothing: A bright blue dance leotard with a blue and lime green tutu (silver ribbons on tutu)
Shoes: Ballet shoes
Accessories: Muggle-style fairy wand

She looked over her notes, happy with what she'd come up with. She could probably manage to make a drawing of the costume with the details she had.
