To Do Friday: Un Ballo in Maschera

Maggie Betts.

Maggie Betts.

Get your masks out, because the social swans are covering their professionally made-up mugs to raise money for Save Venice, benefiting the city that is sinking faster than Lindsay Lohan’s bank account. The theme is very Truman Capote: a black-and-white masquerade ball—perfect for girls to show off those Op Art Marc Jacobs for Louis Vuitton dresses. The benefit committee is a who’s who of young boldfaced names like Maggie Betts, Hayley Bloomingdale, Trisha Gregory, style icon Michelle Harper (who will probably win the Best Female Mask prize), Stavros Niarchos and Jessica Hart, Julie Macklowe, Annelise Peterson and Lauren Santo Domingo.

The Pierre, 2 East 61st Street, (212) 838-8000, cocktails 8pm, dinner 9pm, by invitation only.
