THE SCOOP: Modern '50s, but not too retro, was the scene at Christian Siriano -- think evening-chic pompadours, strong eyebrows and statement lipstick to complement his collection of glam evening gowns, cocktail dresses and slick skinny pants.

GET THE LOOK - MAKEUP: "The main focus is the beautiful, defined brow," said lead makeup artist Darcy Louise. Instead of being a block of solid color, it was "about the wispiness of a brow. Use a brow pencil and 'flick' up from the bottom," she said. Creamy-matte lipstick in fuchsia courtesy of Lavish lipstick by Victoria's Secret Beauty.

GET THE LOOK - HAIR: Beenders teased the hair at the roots to create volume at the crown before pulling it back into a bun. He kept the models' hair in place with Aveda Control Force Hair Spray, a new firm hold spray launching this summer.
