As of May 12, the company is streamlining its dress code to play up its signature branded green apron. Per the coffee chain’s new mandate, baristas will wear any black short- or long-sleeved crewneck, collared or button-up shirts with khaki, black or blue denim bottoms. Starbucks will be serving up two branded T-shirts for employees — at no charge.

Starbucks has brand guidelines about its signature green color. Now that extends to employee dress. Starbucks baristas will soon have a new dress code that’s meant to center the coffee chain’s signature brand color.
