Kate Middleton Surprises Again With Emerald Gown

Kate Middleton has officially stepped outside of her fashion comfort zone!

In London Friday, the Duchess of Cambridge worked the red carpet at the BOA Olympic Concert dress in a stunning emerald Jenny Packham pleated gown.

The design, which featured a low-cut neckline and a sheer, lace back, is accented with a crystal-adorned ribbon that cinched the royal's waist. Take a look:

The 30-year-old fashion icon paired the breathtaking dress with Jimmy Choo "Vamp" platform glitter sandals and a matching Jenny Packham bespoke clutch.

The more-revealing-than-normal number wasn't her only new look this week. Kate Middleton's dress earlier this week turned heads due to its slit up the leg.

Kate, who arrived hand-in-hand with her husband Prince William, wore her hair in an elaborate braided chignon that ensured the dress' sheer back was on display.

Another resounding style win, wouldn't you say? For many more of the fashionable royal's looks, follow the link for THG's gallery of Kate Middleton pics!
