Hermione and Draco

It was New Year's Eve at Hogwarts, and Dumbledore had decided to throw a New Year's Eve ball, so Draco decided to invite Hermione, not sure why. As she was descending the stairs into the hall, he met her: he was wearing a black suit—or, to put it simply, a perfect one—and Hermione... Her dress had a fitted bodice with draping that accentuated her silhouette, and a full, softly pleated skirt that flowed into a light train. Her dress was off-the-shoulder, with a decorative strand of pearls on one shoulder. The long sleeves were voluminous, with draped cuffs. The fabric looked flowing and smooth. The overall look was distinguished by sophistication and airy lightness. This dress was beautiful, and Draco was simply mesmerized by its beauty.
