[All photos by Joe Schildhorn for PMc] Claire Danes, Ivanka Trump, Charlotte Ronson, Michelle Trachtenberg, Tinsley Mortimer, Ali Wise, and other guests got dolled up in their finest dresses and flocked this year's Lilly Pulitzer-sponsored Museum of Natural History gala to dance, drink, and ogle dioramas.-

Also in attendance were Zani Gugelmann, Matthew Settle, Christian Siriano, and Emmy Rossum. Judging from the plethora of Pulitzer prints and the dance's signature drink - the "Pink-Greeni”, with Double Cross Vodka, grapefruit juice, and a lime twist - Lilly Pulitzer should host every year's event.
