Mark Badgley and James Mischka tie the knot

After 28 years as a couple, designer duo Mark Badgley and James Mischka tied the knot at New York City Hall on Friday.

The only witness at the ceremony was Badgley's twin sister. However, the happy couple gave the public a glimpse of the nuptials and shared a photo of their wedding bands on Twitter. According to WWD, they held a private celebratory dinner with an intimate group of 22 friends and family members at a SoHo restaurant.

The two met at Parsons School of Design and found an overlapping interest in fashion - and each other. In 1988, Badgley and Mischka launched their eponymous joint-label, Badgley Mischka, and debuted their bridal line just five years later. Sex and the City's Charlotte York played by Kristin Davis famously chose the label for her second wedding. Badgley Mischka's designs are also frequently worn by red carpet staples like Brooke Shields, Kelly Osbourne and Oprah Winfrey.
