Rachel McAdams in Alberta Ferretti

We have a confession to make: we have a new red carpet crush, and her name is Rachel McAdams. Channeling the understated elegance of Hollywood screen siren Lauren Bacall, Rachel wore a gorgeous vintage inspired outfit at the Sherlock Holmes Premier in Berlin this week.

Wearing an Alberti Ferretti floor length gown Rachel wowed on-lookers as she appeared every inch the old-school icon with perfect poise and side-parted set and wave curls. The asymmetric dress from Alberta Ferretti’s fall 09 collection gives her look a contemporary feel and the teal colour of the gown looks particularly stunning against Rachel’s simple makeup and classic red lips.

While there might not be much out there to rival the exquisite design of her Alberta Ferretti dress, you can always achieve Rachel’s retro look with carefully styled hair and makeup.

Rachel’s red lips are the key to her screen-siren appeal and the best choice to achieve a similar look is Chanel Rouge allure lipstick in classic red ‘Lover’. Packed with shea butter and oils this intense lipstick will give your look an instant colour hit as well as keeping your pout moisturized.

Keep the rest of the face simple with matte skin and just a coat of mascara to finish and you may well rival the Hollywood icon yourself. Chanel Rouge Allure Lipstick, £21.97 available from Boots.
