An unstructured blazer in a grey-and-green gingham check pattern with blue accents running through the weave. The color palette blends cool grey, sage green, and muted blue for a sophisticated, layered plaid. Notch lapels, a two-button front, and flap pockets keep the shape classic. A pocket square peeks from the chest pocket, and a branded patch sits on the lower sleeve.

Made from lightweight, unlined fabric with a natural drape, this blazer moves easily and stays comfortable through long days. The unconstructed shoulders give it a relaxed European sensibility.

Conceived in Paris and precision-fitted through an MIT algorithm calibrated to 30 million body types, this Descartes blazer achieves a proportioned silhouette that bridges smart casual and West Coast cool.

Dry clean recommended. Available in sizes S to 5XL.
