For the fourth season in a row, Scarlett Johansson and photographer Mario Sorrenti have teamed up for some sexy Mango ads.

This time round, for the Fall 2010/Winter 2011 season, stylist Camilla Nickerson, makeup artist Stéphane Marais, and hair guru Oribe (who styled Johansson's locks for her Dolce & Gabbana campaign) also joined in to create the mod, moody ads that are accented by colored lights.

Johansson appears with long, sexy auburn hair (a la Kristen Stewart) and sports the Spanish retailer's fall collection, which the company says was inspired by British country style and English staples such as trench coats, thick, handmade knits, double-breasted jackets, and sharply tailored coats.

That influence is also said to be combined with the idea of the freedom of style embodied by actresses such as Anjelica Huston in the late '70s, when the rich textures of tweed, corduroy, and fur were mixed with flowing silks, long skirts, wide trousers, and cinched waists.

However, if you ask us, the ads skew more "Mad Men"-era '60s.

In the two images that have been released, Johansson, whose famed curves have been playing hide-and-seek of late, shows off her enviable hourglass figure in a printed frock that's cinched at the waist, as well as a body-skimming and belted gray knit dress that looks like something "Mad Men" siren Joan Harris would wear.
