Carey Mulligan Is Obsessed With Shirt Dresses (& You’re About To Be, Too)

Carey Mulligan rarely strays far from her signature ultra-feminine style. The actor lives in floral prints, A-line cuts, and collared necklines, favoring a single piece in particular that combines all her favorite features in one. Carey Mulligan's style will inspire you to stockpile shirt dresses for a fail-proof, polished look this fall.

On Mon., the actor appeared on Today alongside Jake Gyllenhaal to talk about their latest film, Wildlife, which hits theaters Oct. 18. Mulligan wore a full-length pink shirt dress with puffy three-quarter sleeves. The fuchsia frock features ruffled pockets and a belted waist and Mulligan paired it with black cut-out, spiky-heeled booties. After a summer of shirt dresses for the Great Gatsby actor, her most recent outfit is all the proof you need that this wardrobe staple can absolutely be worn into cold-weather months.

Mulligan's shirt dress spree began in June, when she turned up to The Royal Court Theatre Production of Girls and Boys at Sardi's in New York wearing a cream-colored button-up dress with billowing sleeves. The classic white shirt dress features a bow-tie belt at the waist to break up the menswear vibe.

Since then, the 33-year-old has worn shirt dresses in a slew of styles. As the temperature drops, her sleeves and skirt lengths get longer, but nonetheless, the trend still works. Meghan Markle, Katie Holmes, and Sienna Miller have been sporting the same look as of late, too. A long-sleeve shirt dress is the key to looking put together without much effort this fall. Ahead, four Mulligan-inspired shirt dresses that are post-summer approved.

The Vibrant Shirt Dress

Color is on-trend this season, as Mulligan's latest look shows. A full-length skirt and long sleeves help make bright colors autumn-appropriate. The actor opted for fuchsia this time, but mustard yellow and olive green are so in — just take a look at the sage-colored shirt dress Meghan Markle wore in Sydney on Tues.

The Collarless Shirt Dress

During a Sept. 10 press conference for Wildlife, Mulligan wore a collarless sunny-yellow shirt dress with a wide belt around the waist and big ruffled sleeves. The A-line cut and frilly details suited the actor's feminine style perfectly. She paired it with subtle black flats, but you could make the look more casual with a pair of white sneakers instead.

The Printed Shirt Dress

Printed maxis are a must for any fall wardrobe. Sienna Miller just wore a $70 plaid shirt dress from Zara that made everyone swoon and Mulligan recently sported a bright-red snake print frock from Mango in London. This season, opt for check patterns, animal print, or florals in fall tones paired with your favorite ankle boots and a leather jacket.

The White Shirt Dress

They say not to wear white after Labor Day, but that rule doesn't apply here. A basic, menswear-inspired shirt dress is a wardrobe essential that can be worn year round. Aside from Mulligan's girly version back in June, Katie Holmes even wore a crisp, loose-fitting button-up to New York Fashion Week in Sept.
