Keep it casual in Brixton's micro stripe navy and blue polo shirt. This tee's soft polyester-and-cotton construction keeps it lightweight and comfortable, while the fold-down collar and three-button placket blend a business-casual element into the mix. With a navy-tinted collar offering up a little contrast against the horizontal navy-and-blue stripes descending down the shirt, this top will lend any look you craft a dash of subtle, colorful detailing.
