Apparently, the batch consists of stars like Sienna Miller and Katie Holmes, who, along with an epic A-list set, gathered inside Tribeca’s Locanda Verde restaurant for lunch on Tuesday in New York in celebration of Through Her Lens: The Tribeca Chanel Women’s Filmmaker Program. As its name implies, the program seeks to uplift female directors, writers, and leading women in the industry, which is why we were quite impressed to see a solid turnout, especially with Miller's appearance.

Her beauty look consisted of a wavy 'do and a natural-looking glow. Gonzalo Marroquin/Patrick McMullan In addition to Miller, Holmes also wowed in an elegant, '50s-inspired outfit. She paired a classic navy blue sweater with an A-line skirt and minimal accessories that packed a punch. Dimitrios Kambouris/WireImage Katie Holmes's Enjoys a Breezy N.Y.C.
