Christian Siriano is The Little Mermaid's Ariel

Christian Siriano dresses up as The Little Mermaid‘s Ariel as he hosts the “Heroes vs. Villains” Halloween party at Gramercy Park Hotel’s Rose Bar on Saturday (October 31) in New York City.

The 23-year-old fierce fashion designer was accompanied by his boyfriend Brad Walsh, who was Christian‘s prince charming, Eric. It apparently was a Disney night as Ursula was at the party also!

The event was also hosted by PR gurus Lauren Auslander (Rosie the Riviter) and Bianca Bianconi (Cleopatra) as well as gallery owner Mazdack Rassi and Rose Bar’s creative director Nur Khan. Also pictured below: Alexa Chung and Agyness Deyn as Wayne and Garth from Wayne’s World.
