In the few weeks they had time to prepare, Dark and Daizi spoke extensively about what they'd want to wear. Something cohesive, certainly, but what? At first, they discussed dressing more aligned with Daizi's celestial, ethereal intereste, but they didn't have the time, or money, to commission a fitting suit for Dark. Instead, they decided it was the perfect time to commit fully to Dark's vampire aesthetic.
Daizi wore a dark red, velvet, drop-waist gown with princess seams down the front. It off the shoulder, with black lace like a cathedral lining the neckline, and the sleeves themselves reached the floor. Their hem, and them of the rest of the dress, shifted elegantly to a brighter red hue.
Meanwhile, Dark went with his ruffliest, most vampiric shirt, black pants, and a red double-breasted waistcoat with gold buttons. Over it, he donned a one-shoulder cape, held together by a gold chain, and over the side where the fabric wasn't were leather feathers.
For masks, Daizi wore a mask without any eye holes. It was gold and decorated with red gems, and skeleton hands. Dark's was a more simple, classic, gold Phantom of the Opera style mask.
Due to the nature of Daizi's mask, she didn't have much eye makeup on, but Dark still put enough on her so, if she did ever remove her mask, her aesthetic would still look complete. Her lipstick, though, was a gradient which matched the gradient of her gown. For his part, Dark applied a tasteful amount of eyeliner and perhaps indulged slightly in a bit of contouring.
