Polished Classic style

Polished Classic is the style most dress codes were built around, which is why it works almost anywhere: an office, a dinner, a wedding where you're not sure how dressed up to be. It's tailored-leaning rather than formal. A navy blazer over an Oxford shirt with grey trousers is the classic version; a navy sweater over a white shirt with chinos is the relaxed one.

The way it goes wrong is stiffness, where everything matches and nothing looks worn. One casual piece, like dark jeans with the blazer or loafers instead of dress shoes, usually fixes it.

Where this definition comes from

The menswear side has the most consistent sources of the six. Derek Guy at Put This On calls navy sport coats the workhorses of business casual and pairs them with light-to-mid grey trousers, white and light blue shirts, and dark brown derbies. At Die, Workwear! he names the light blue Oxford-cloth button-down the most useful shirt you can own. Wikipedia's history of Ivy style traces the same set of blazers, Oxford shirts, chinos and penny loafers back to mid-century American campuses.

Womenswear rests on fashion-press consensus around one well-known book: Inès de la Fressange's Parisian Chic, whose basics (blazer, trench, navy cashmere, straight jeans, a black dress) I confirmed through its Goodreads page and reviews rather than the book itself, and SheerLuxe's list of Parisian wardrobe staples. That's a weaker tier than the menswear sources.
