Ah, spring. First come the Park Avenue tulips, next a herd of women donning festively festooned chapeaux making their annual pilgrimage to lunch in Central Park...

Yesterday, the Central Park Conservancy’s Women’s Committee hosted their Frederick Law Olmsted Awards Luncheon, raising $4.3 million to support the park. More than 1,250 guests stepped out for the afternoon affair held in the Conservatory Garden, with everyone from Michael Bloomberg, Misty Copeland, Katie Couric, Mariska Hargitay and Nina Garcia to Gillian Miniter, Martha Stewart, Ali Wentworth, and more sporting, as is tradition, spring-inspired hats for the occasion.
