Women's Suits Built on our foundational tenets of fit, fabric, and functionality, our women’s suits are designed to change the way we feel and improve the way we work. Meticulously constructed to create a superior fit and produced using the industry’s finest, most enduring fabrics, each suiting piece—whether worn together or separately—epitomizes American sportswear by marrying a timeless appeal with modern mix-and-match versatility.
All Theory women’s suits are sold as separates to allow our customer to customize her wardrobe with the essential pieces and silhouettes that best correspond to her person style—be it the structured single-breasted blazer for work or a formal occasion, tailored yet casual pants for WFH, the ubiquitous black suit, a more of-the-moment fashion suit, or a laid-back menswear-inspired suit.
Our renowned suits span a range of fits from classic, such as the fitted blazer or Staple blazer and Treeca pant or Demitria pant, to modern silhouettes, such as the double-breasted blazer or Etiennette blazer and Terena pant. Our fabrics offering is just as versatile. If you’re looking for a timeless, all-seasons suit, look to Good Wool: responsibly crafted in ultra-fine merino wool woven with ample stretch for a soft, lightweight feel that’s wearable year-round and resists wrinkles. Our new Sleek Flannel fabric combines a polished look with a comfortable feel, while plaid wool and leather offer a fashion-first approach to suiting and an easy way to refresh your workwear.
