Theory Wardrobe
Elevated essentials, designed for a lifetime.
A well-curated wardrobe starts with versatile, indispensable pieces. Defined by precise tailoring perfected in our New York atelier and premium fabrics sourced from the world’s best mills, the styles in our Theory Wardrobe edit are our most sought-after pieces. Available year round, these bestsellers simplify the act of getting dressed, allowing you to focus on what matters most—achieving your goals and aiming for perfection.
Your Go-To Tee
Airy, soft organic cotton meets a considered, pre-shrunken fit in our bestselling Tiny Tee. A lightweight, throw-on-and-go staple, it’s an essential you’ll want in every color.
Your All-Season Suit
Everyone needs a polished suit on standby. With menswear details and a feminine fit, the Carissa Blazer is an ideal complement to our leg-lengthening Flared Trouser.
Why We Love: Good Wool
Woven at the Tollegno 1900 mill in Biella, Italy, our tropical-weight Good Wool fabric is crafted with premium Australian merino fibers and a hint of stretch.
A No-Brainer Dress
Made up of strategically placed panels for a fit that flatters from every angle, this streamlined silhouette is tailored for the perfect second skin fit.
The Cigarette Trouser
A desk-to-dinner icon that elevates your every day, our bestselling Treeca Trouser features a sharp slim leg and cropped hem.
Effortless Crepe Essentials
The pull-on version of our bestselling Treeca Trouser and our light, layerable Oaklane Trench take on an elegant drape in smooth, sophisticated Admiral Crepe.
Why We Love: Admiral Crepe
A fabric that looks polished from your morning commute to post-work drinks, our elevated Admiral Crepe is woven in Japan.
The featherweight Sweater
As light as a tee and as soft as a sweater, this premium merino wool layer is a must. Detailed with short sleeves it has year-round layering potential.
Why We Love: Regal Wool
Crafted with a featherweight yarn, our Regal Wool has a lustrous finish and cashmere-like feel without the weight. Using merino wool sourced from the Congi farm in Woolbrook, Australia, this breathable material is spun and knit by the Botto Giuseppe mill in Biella, Italy.
Sophisticated Silk Tops
A luxurious update to the traditional button-up, our fitted shirt highlights the waist, while our sleek shell top is a fuss-free styling essential you’ll want in every color.
Why We Love: Silk Georgette
Our Silk Georgette is MADE IN GREEN by OEKO-TEX® certified, meaning it’s crafted without harmful chemicals, in environmentally and socially responsible facilities.
