Zac Posen, fashion designer to the stars, brought some limelight to Toronto this week as he showcased his fall collection – and his dance moves! - to help raise money for a children's charity.

The American entrepreneur, who has dressed the likes of Naomi Campbell, Uma Thurman, Rihanna and Lena Dunham, collaborated with philanthropist Suzanne Rogers for a glitzy event held at the historic Carlu, which featured an exclusive fashion show and a big-ticket auction.

With the help of his supermodel friend Coco Rocha, who encouraged Zac to dance onstage to Liza Minnelli (all for a good cause, of course), the gala raised more than $800,000 for Boost, a child abuse and intervention program.

Hello! Online caught up with the 33-year-old designer at his exclusive Holt Renfrew trunk show, where Zac relived the night’s revelries and revealed the inspiration for his latest red-carpet worthy looks. Watch the video below!
