Lucky for those who've already spent more than they'd like to admit on their fall wardrobes, Sienna Miller's plaid shirt dress is about to be your favorite find of the season. The British actor wore the perfect, ankle-grazing dress while out and about on Thurs. in New York City, and emulating her style has officially never been easier. Not only is Miller's dress a cool $70 — but it's still available at Zara right now.

There's nothing to dislike about Miller's dress: It's a long-sleeved midi with a relaxed A-line fit that's slightly tapered at the waist. In typical Miller fashion, she paired the look with chunky, black ankle boots (with cozy, wool socks peaking over the top) and carried a floor-length, emerald-green jacket. Needless to say, the actor's look summed up exactly what you should wear on the perfect, 70-degree autumn day.

This isn't the first time Miller has ditched a designer label for an off-the-rack find. In June, she wore a $40 blue-gingham summer dress from H&M with sunny yellow flats. And just before that, she gave her seal of approval to budget-friendly brand B Collection by Bobeau, wearing two of its pieces (a $78 jumpsuit and $68 blouse) within the same week.

Get The Look

The celebrity set is no stranger to the shirt dress — remember Emily Ratajkowski's long-sleeve henley dress from New York Fashion Week? And celebrities like Miller and Katie Holmes (who wore a crisp white menswear-inspired shirt dress to NYFW) are beginning to transition the look into their fall wardrobes, too. Miller's outfit makes it official: The shirt dress is a fuss-free, all-season trend — and there's perhaps no easier outfit for a crisp fall day than this single-item staple.

The beauty of a shirt dress is that they're incredibly comfortable. Opt for loose-fitting silhouettes and pair your dress with ankle-high boots or throw on a pair of mules for an elevated look. Shirt dresses don't have to look lazy, either — a collared shirt dress pairs well with pumps and heels for a handful of formal settings (even the office).

If you're on board with Miller's easy look, then you should make some room in your closet for a few versatile shirt dresses — and do it quickly, because the actor's Zara piece isn't going to last long. Ahead, The Zoe Report's favorite shirt dresses of the moment to recreate the look yourself.
