Sarah Jessica Parker threw on a vintage Oscar de la Renta ball gown, paired with a cardigan, to attend last night's Carnegie Hall Medal of Excellence gala at NYC's Waldorf-Astoria. The event was held to honor legendary New York Times photographer Bill Cunningham, who was the subject of the 2010 documentary Bill Cunningham New York. Bill was there to receive his praise, some of which was provided by Vogue's Anna Wintour and Hamish Bowles. In addition to honoring Bill, who spoke about his lengthy career, the bash raised $1.5 million for the music education programs at Carnegie Hall. Arts education is a cause SJP is particularly passionate about. She announced yesterday that she, along with other celebs like Kerry Washington and Forest Whitaker, are teaming up with President Obama to help increase student achievement at underperforming schools in the US by donating funds to increase access to arts programs.
