Old money style is the quiet kind of dressed up: cable knit sweaters and turtlenecks, satin and pleated midi dresses, cotton button-front blouses, wide leg trousers and faux suede skirts, finished with loafers, knee-high boots and a pearl or gold earring. The palette stays to ivory, camel, chocolate, navy, burgundy and black, with the occasional plaid.
If you shop by the words quiet luxury or old money, this is the same closet: nothing loud, nothing with a logo, everything that still looks right in ten years. For the office, start with Work Dresses; for the layers, Cardigans; for the finish, Knee-High Boots and Loafers.
