Backstage at the Christian Siriano Fall 2011 collection, a clean and neutral face paired with beach-soft waves was among the most achievable looks we've seen at New York Fashion Week.

THE SCOOP: While Christian Siriano's Fall 2011 collection ran the gamut from classic little black dress to over-the-top feathered gowns, makeup and hair stayed simple and consistent, with a bare face and waves created with braids.

"It's just gorgeous simpleness, highlighted by a Brooke Shields eyebrow," Osmond told StyleList. Brows were brushed upward to look fuller and lightly darkened, and the rest of the face was kept nude, save for the most subtle smudge of mauve gloss on the lips. Clear gloss also created a dewy finish on lids and atop cheekbones.

For authentic-looking waves, hair was sectioned off, braided and then clamped down on with a flatiron to quickly set. After cooling, a brush-through yielded the look of slept-in-my-braids waves. "It's so easy to do at home, which is a nice change. It's rare I do something like this during Fashion Week!" said Beenders.

Models with finer, straighter hair texture kept their braids in for longer, while nibbling on a backstage spread of falafel, roasted veggies and couscous provided by City Bakery.

GET THE LOOK - MAKEUP: All products by MAC. Only neutralize needed skin areas with concealer, and then highlight cheeks and eyelids with shine gloss. Lightly darken brows with Tinted Brow Set gel, brushing in an upward movement to make shape fuller. "Go lightly on the brow gel -- it's like hair dye," advises Osmond.

Curl lashes to further open the eye, and apply a couple of coats of Opulash Mascara to the top lash lines. Conceal the natural hue of the lip, and then apply Up Til Tomorrow lipstick topped by Good Times Lipglass for a natural mauve tone.

GET THE LOOK - HAIR: Spray Aveda's Control Force hairspray on locks before dividing into equal sections and braiding, taking care to start no higher than the eye and not to pull too tightly. Tie an elastic at the bottoms, and then tap open-and-closed a flatiron down the shaft, holding for one second before opening and closing again. Then pull the hair gently out of the braid, and repeat the flatiron process again. Once hair has cooled to the touch, take out the braids and lightly brush through for believable soft waves.
