Join members of Post:Ballet for a dance party cum fashion show Sunday at Raven in SoMa. It's called Arty Party, it starts at 4 p.m., and it's not just a party.

There will be music by DJ B-Hall, a photo booth, and members of the ballet company modeling designs by Susan Roemer of S-Curve Apparel & Design, as well as avant-garde accessories by Christian Squires that everyone can try on. There may even be some modern-dance-style go-going.

The event is a fundraiser for Post:Ballet, which if you don't know it, you should. The company, headed by Robert Dekkers and now in its fifth year, is an acclaimed force in innovative, modern ballet with national recognition.

Tickets for Arty Party are $25 and are tax deductible. More info here. Below, a video of Post:Ballet's piece "When In Doubt."
