Mad Men returns to our screens next week for its sixth season, moving into the late 1960s.
And snaps from the new episodes reveal the costume department has fully embraced the fashion of the times with hippy florals, beehive hair and more daring colours.
This season, old favourites Betty Francis (January Jones), Joan Holloway (Christina Hendricks) and Peggy Olson (Elizabeth Moss), as well as season five newbie Megan Draper (Jessica Paré) are set to embrace Summer of Love-era style.

The boys get a look in too, with sideburns getting longer and even conservative (if snappy) dresser Don experimenting with colours and tweed suits.
But it's the ladies we're really interested in. It's the flower power era, with Twiggy at the height of her fame, and the Mod movement going global.
The Mad women get to experiment with Mary Quant style mini dresses, wide-eyed make up and big hair.
Jessica Pare embodies the youthful energy of the period, opting for the most stylish designs as she aims to pursue an acting career.
Staying true to her character and making the most of her fabulous hourglass figure, Christina Hendricks as Joan Holloway sticks to classic tailoring but begins to mix up her styles with added ruffles and accessories.
And thought there are no stills out yet, of course we're all wondering how don's ex-wife Betty is getting on (and whether she's lost the weight she mysteriously gained during the last season thanks to actress January Jone's pregnancy). Mad Men returns to UK TV screens on April 10th on Sky Atlantic. We are beyond excited.
