Episode 2.7 was so action-packed that its sartorial genius may have escaped your notice. We were awed by the fashion on display, a departure from the show’s usual low-key style. Bonnie and Caroline’s gowns at the Masquerade Ball were particularly fetching, and they sported a trend that’s hot, hot, hot — the one-shoulder look.

One-shoulder dresses are the best of both worlds: the appeal of strapless, with the comfort and mobility of straps. Remember: Holiday parties are right around the corner. Why not try it yourself? Here’s how:

Caroline: Lady in Red

Caroline’s fiery red number is sexy siren meets Grecian goddess. The flowing top is offset by the gathered waist, and the asymmetrical hemline adds detail. Draped fabric flatters a variety of body types, and red is ideal for holiday fêtes. Get this look for only $76.61:

Bonnie’s Pattern Play

The patterned fabric of Bonnie’s dress makes for gorgeous ruching down the sleeve, and the tulip bottom is trés chic. You can’t go wrong with a classic black and white combo. Score yours for a ridiculously low $39.50, if you act fast:
