Marlene/?
Marlene wanted to go to the party to see what they had done. Not that she ever wanted to skip a party, but after all the problems with Jamie's, she was eager to see how they had gotten around the limitations. So she had gotten dressed up in a simple black dress with silver accessories. It was more sobre than she liked, but this was Regulus, and it was Remus, and they were the Malfoys. She could be nice on occasion.
When she got there, it became obvious that they hadn't. Everything was impeccable, and she knew that she's have to find Alastor sooner rather than later. However, until then, she was planning on enjoying the food and drinks.
