Theory Blazers

Theory's Gabe cut runs narrow through the shoulder -- a size two here fits closer to a zero in most workwear labels.

Theory's collarless Clean Blazer in Organic Crunch Wash linen -- the cut that defined early-2010s minimalist dressing for working women, now priced where basic suiting usually lands.

Theory's Etiennette cut -- the single-button longline that defined mid-2010s office dressing -- sits at the edge of where used ones cluster.

Theory's DB Boy blazer in double-faced virgin wool -- the cut that defined mid-aughts minimalist dressing for working women.

Theory's Good Linen blazer, the piece that built the brand's office-to-anywhere reputation in the early aughts, priced where cotton basics usually sit.

Theory's Trecca cut in olive linen-blend -- a longer, relaxed silhouette that moves against the brand's sharper office reputation.

Theory's Parmenia cut with four-pocket construction, a detail that narrows the field for buyers who want utility without bulk.

Theory's Brince tweed blazer sits in a crowded field of office-to-evening jackets where the brand's own deep resale supply competes against itself.

Theory's Rosina crepe -- the fabric that made the label's name in midtown offices -- cut here in the shawl-collar blazer that defined its early aughts silhouette.

Theory's Eco Crunch wash -- the rumpled linen finish that defined downtown tailoring in the late aughts -- here in the double-breasted boy cut that built the brand's following.

Theory's relaxed tweed cut, open-front and unstructured, sits outside the brand's sharper office-core reputation.

Theory's City blazer—the cut that made the brand the reference point for modern workwear—here where two months without a sale has pulled the ask below where these wool staples usually change hands.

Tweed blazers from Theory carry a fitted block that runs trim through the shoulders -- worth knowing before the size two tag seduces.

The Gabe B is Theory's most borrowed silhouette, yet excellent used examples vanish quickly into working wardrobes rather than resale.

Theory's Angled Jacket is the cut that launched a thousand office wardrobes -- the same architectural lapel and nipped waist that made the brand a verb in midtown corridors.

Theory's leather-trimmed tuxedo cut is a deliberate departure from the brand's office-standard tailoring, and the secondary market has never settled on how to price it.

Theory's tweed Dancey cut surfaces rarely in this size, a shape that sits outside the brand's steady suiting rotation.

The Nillian cut is what office-dressing veterans still name-check when they talk about Theory's early New York years.

Theory built its following on precisely this kind of architectural minimalism -- the no-button closure that reads as restraint rather than omission.

Theory's crepe blazer in a size that runs smaller than the label suggests.

Theory's Power Jacket built the brand's reputation on a single sharp-shouldered cut that defined early-aughts office dressing.

Theory's Gabe blazer -- the cut that defined midtown uniform dressing for a decade -- in the wool houndstooth that rarely appears secondhand.

Theory's navy linen-blend tailoring arrives in a size that moves fast when it does appear.

Theory's Laseli cut carries a raw fringe hem that continues the plaid pattern uninterrupted -- a tailoring choice that reads as intentional finish, not afterthought.
