Sienna Miller looks en Vogue at “September Issue” Premiere…I totally love Sienna Miller’s hairstyle, the dress, the golden shoes, and the sunglasses. Probably something I would wear. So Marta:)

Yesterday marked the New York premiere of the hotly anticipated “September Issue” – a documentary following legendary Vogue Editor-in-Chief Anna Wintour. Walking down the red carpet in style at the premiere will be actress and fashion icon Sienna Miller, who graced the cover of the magazine’s largest issue for which the film is named.

With the help of celebrity hair stylist Kevin Mancuso, Miller was  looking “en Vogue” by showcasing one of this season’s best trends – disheveled glam.

If you are looking to recreate a Sienna Miller inspired look at home, Kevin offers his step-by-step styling tips for this red carpet look below.

The Look: Hair is worn down with loose, bohemian-chic waves

Prep: Enhance your natural texture by applying a volumizing or curling mousse, such as Nexxus Mousse Plus

…or Nexxus Gorgeous Curls, at the root and spreading to the ends. Flip head over and blow hair around while massaging the roots with your finger tips. This will help build texture into the style.

Retro ruled the red carpet last night, with 30s, 40s and 50s glamour on display. Smooth waves and constructed pinning ushered in new, softer styles that were timelessly elegant.

Kevin Mancuso, Creative Director for Nexxus Salon Hair Care, created the modern and romantic updo worn by presenter Natalie Portman. With a sweeping side part and soft curl, pinned into a beautiful knot at the nape of her neck, the look was deceptively easy to create. Kevin described how to get the look below in a few simple steps.

How-to Get Natalie Portman’s hairstyle at Oscars 2009:

Step 1: Apply a volumizing styler to the roots, like Nexxus Root Exxtend, to add body into the hair.

Distribute a medium-hold mousse, such as Nexxus Mousse Plus, throughout hair to and maintain and support the structure of the style. More modern updos employ product instead of teasing to build body, for a softer, healthier look. Blow dry hair with a large round brush, concentrating on the ends to smooth the hair.
