We like to think of the ’60s mod trend as an homage to the final season of Mad Men. (Sob.) However you choose to see it, designers are embracing throwback threads, and we’re totally on board. From mini shifts to prim collars and high-neck sweaters, many of the swinging looks—available at women's boutiques in Chicago and even vintage stores and thrift shops—from the decade are back. Bonus points if you accessorize with a classic cocktail.
