Kate Middleton is the epitome of elegance, but that doesn't mean she hasn't taken a few fashion risks here and there. Many of the Duchess of Cambridge's royalty-appropriate outfits have sheer details that have definitely turned heads. Her key to choosing palace-worthy looks is sticking to dresses with sheer elements rather than going all-out with the trend. Translation: She chooses dresses with a transparent back or see-through sleeves. (Don't expect to see the naked dress trend in Kensington Palace anytime soon.)

One of her most daring looks, for instance, was a black Temperley London number with cutout sheer sleeves that showed strategic hints of skin. For a red carpet event recently, she also wore an ethereal Jenny Packham gown that featured floaty sheer sleeves and a beautiful gossamer back. Scroll down to see how she's worn hints of sheer details and to shop the trend for yourself.
