US pop star Taylor Swift enjoys holding parties. But for the last few years, she hasn’t held many. Now the party girl is back. She held a costume (服装) party on New Year’s Eve in New York. The party’s theme (主题) was “dress like your childhood hero (英雄)”. Taylor dressed as the mermaid (美人鱼) from The Little Mermaid. Her friends, including US actress Blake Lively and US model Gigi Hadid, went to the party.
