"Everyone just knows that tonight is consistently the most fun party of the year!" event cochair Alexandra Lebenthal announced at the New York Botanical Garden's annual Winter Wonderland Ball on Friday. That seemed to be the sentiment shared by most of the guests who traveled to the Bronx for the party; philanthropy-scene fixtures and fashion folk alike were dressed to the nines. Showing off a diamond ear cuff to some admirers, Sally Perrin said, "I don't have much jewelry, but what I do have is really, really good." Perrin Paris 1893 and Bergdorf Goodman were the evening's sponsors, and the event raises funds for the Garden's Children's Education program. Gillian Miniter, a longtime supporter of the Garden, remarked how difficult it can be to keep up with dressing for so many events. "I had to start shopping from the showrooms, because I've had that happen to me, and it's humiliating." She was referring to two women who, for the "Winter White & Black" theme, wore the same Marc Jacobs Spring 2013 checkered dress. It didn't seem to matter, though, as the evening grew late. The lively dance floor was full until well after midnight. In the center of it all: the two women in matching Marc Jacobs.
