Kate Middleton -- revered as one of the greatest fashion icons of 2011 -- has been crowned Hat Person of the Year, by the Headwear Association.

The Duchess of Cambridge received 91 percent of the vote, ahead of Rachel Zoe, Ne-Yo, Justin Timberlake, Bruno Mars and Charlie Sheen.

Middleton is renowned for accessorizing her outfits with various hats. A Jane Corbett magenta hat that Middleton wore during her first Royal Christmas at Sardingham, was a global favorite. It made headlines for the way it complemented her plum-colored fitted coat and gold drop earrings.

The Headwear Association was founded in 1908 and is the oldest fashion trade association in the industry, according to the organization's Web site. The Hat Person of the Year award has been ongoing for the past three years and previous winners include Johnny Depp and Brad Pitt.

The Headwear Association mentioned the following hats as their favorites:

A red maple leaf headpiece worn by the Duchess at a Citizenship Ceremony, in Quebec. The hat was designed and made by Sylvia Fletcher of London milliners Lock & Co, established since 1676.

Middleton's Christmas Day mulled wine hat, worn at a church service at Sandrigham. The hat was designed by Jane Corbett, who was trained by Rose Cory, the Queen Mother's milliner.

There was also a black felt beret from Whiteley Fischer, a British hat manufacturer who has been in the millinery trade for more than 60 years. The hat was worn by the Duchess at a friend's wedding in January.

At the wedding of Zara Phillips last July, Kate wore a hat she actually helped milliner Gina Foster design.
