She was not exactly thrilled about dressing up for Halloween, but after Alice had begged her to dress up, Rosalie begrudgingly dressed up and came out to the party in hopes to see some of her family there.
Walking to the already filling up party, Rosalie knew she would turn a lot of heads with her Goddess Costume. Even if she hated the holiday in general, she figured she would uphold her status as the most beautiful woman in the world, even in a Halloween costume. She was happy that she was with Beckah. The young girl had melted her heart of stone next to Emmett and was glad that the girl would have a fun time, even if Rosalie herself didn't like to dress up in a Halloween costume.
