As ‘Mad Men’ returns this Sunday, we can’t help but look back at style icon Megan Draper’s best looks and wonder what season six will bring in the fashion department.

Megan, played by Montreal-born actress Jessica Paré, has stolen the show’s spotlight with her vast wardrobe of vintage ensembles, from the seductive black mini-dress she wore during her unforgettable 'Zou Bisou Bisou' performance to frocks in eye-popping colours.

What late ‘60s fashion will viewers see in season six? Well, Paré teased "more great costumes and more big hair" in a recent preview. And judging from the season six pictures, we’re likely to see Megan rock psychedelic prints, as well as a floral bikini.

Check out some of Megan’s best looks to date, and see how her style has evolved in the show.

‘Mad Men’ returns for season six on April 7 at 9 p.m. EST/PST on AMC.
