Collared Shirts Are Actually Very Sexy--Here's Why (PHOTOS)

I once had the honor of working with Jamie Lee Curtis on an advertising campaign. The "A Fish Called Wanda" star had strong feelings about what she wore, and rightfully so. She made it clear that she preferred to wear a collared oxford shirt because of the way it framed her face. She was right: The structure of the shirt suited her perfectly.

Collars are very in right now. We've seen them on the runways (Marc Jacobs did them in broderie anglaise for his spring 2012 collection for Louis Vuitton, for example), on celebrities (hello, Alexa Chung) and on fashion insiders (it is Carolina Herrera's signature look).

Our favorite iteration is the Peter Pan version with its soft, rounded edges. Whether you button it all the way up for that nerd-chic look, pop it up on your topper (no one did it better than Nancy Pelosi), or leave it open on a borrowed-from-your-boyfriend oxford, it's stylish.

And it's also extremely sexy. The collar accents your neckline, and if it's open, it acts as a showcase for the new erogenous zone -- your collarbone. (We love collarbones because they barely age or change with weight. What other part of our bodies can we say that about?) Or if you want to appear more demure without looking like a librarian, layer your favorite statement necklace on top for contrast.

If you're not sure about the trend, grab a dickey and try it out under your favorite sweater. And of course, there's the collar-of-all-collars: the trench coat. Wear it with your collar popped and sunglasses and the paparazzi will never catch you.

Here, 35 celebrities in collars, and a few shoppable items to boot.
