Your Perfect Beach Ensemble, Courtesy Of January

You wouldn't expect the actress who plays Betty Draper on Mad Men to have an unabashedly quirky facet to her personality and sartorial choices, but January Jones isn't your typical Hitchcock blond. The actress, model, and mom of one loves to inject a little idiosyncrasy into her life between red carpet appearances and long days spent filming. If you're skeptical, simply check out the ruthless prank she revealed on The Tonight Show Starring Jimmy Fallon's March 29 episode. In her fashion choices too, Jones enjoys mixing vintage elements with modern accents and just enough edge to give an ensemble major fashion kudos.

It was just such an ensemble that Jones posted on Instagram on August 18th, depicted the actress relaxing atop a boat in some dreamy, coastal locale. While the water and unbounded sunshine look utterly enticing, it's Jones' lacy romper, white sunglasses, metallic sandals, and simple golden accessories that are truly captivating. Without a doubt, Ms. Draper knows how to dress herself for a glamorous beachside getaway. What's more, the outfit actually looks comfortable. So if you're hunting for your next sunbathing-in-Ibiza outfit, read on for January Jones' foolproof resort-ready ensemble formula.
