The former child star/current style icon gave twin sister Ashley the slip for the fashion-forward shoot, which has her striking a pose in sequins, a military coat, and feathers in three dazzling cover images (click here to vote on your favorite).

The issue also sees Olsen channeling her inner gypsy woman in a sheer black Giambattista Valli dress paired with a Dolce & Gabbana jacket from which gold charms dangle.

On location at The Inn in Quogue, New York, photographer Tesh snapped The Row designer in a series of images that highlight Olsen's eccentric boho-chic style -- think fur, ankle-sweeping skirts, and effortlessly tousled blonde locks.

Speaking of fur, there's enough of it here to give PETA a heart attack. The 24-year-old starlet wears chunky furs from Marc Jacobs, Doo.ri, Cassin, and Alexander McQueen with everything from a sweet ballerina pink Dior dress and Topshop skirt to a sexy candy-apple red Givenchy dress with matching boots.

The accessories, too, are powerful, ranging from a quirky antler headpiece from Anne Valerie Hash to bling from Stephen Webster.

In between donning some seriously covetable clothing, Olsen opened up to writer Kimberly Cutter about her design career, saying, "It's kind of like a mask to hide behind."

"It took us a year-and-a-half to make the first T-shirt," she says of The Row.

"I still read scripts, and if something great comes along, that's great... but this is my day job.

"The Row is where I go every day."

Does that mean there won't be an "It Takes Two 2"? Say it ain't so!
