It had taken a lot of convincing to get Sif to agree to attend, and that was simply arguing with herself. She had not admitted to anyone else, save the hosts, that she was going; if anyone asked, she only said that she was still thinking on it. And she was for quite some time. She liked seeing her friends, and those she cared about. But Sif had also cultivated a strong desire to be left alone.
Still, she worried about Hedy, and she also rather thought that she should get out more. It was deep in the throes of winter, which was her downtime, and she had no real duties this time of year to make a valid excuse. Perhaps she could enjoy herself a little. She liked to talk. There had to be someone she liked talking with.
She arrived in a green and white flowered dress and an elaborate flowered mask that she felt was earthy enough. She didn't do anything to hide her gold hair; it would be pointless. It shone through every disguise. Instead, she simply pinned it up.
Making her greetings around, Sif was not unaware that Thor and Loki, among others, were there. She couldn't miss them. But each time she saw either, she simply felt a distant bit of emotion that she tamped back down again, before she turned her quiet gaze somewhere else.
