The Marquez shape is a simpler, more pared-down riff on a classic Cuban guayabera. This one is made up in double-striped Italian poplin and makes a great, slightly vintage-feeling summertime sport shirt. The fit is chilled-out and easy — in fact, it's one of the only shirts we recommend leaving untucked — so it's not as slim as our other models, but it also won't swallow you up.
