Starbucks recently introduced a new code of conduct – dress code – for its baristas. This new policy puts severe restrictions on what they’re allowed to wear underneath their green aprons, a far cry from the days — almost ten years ago — when the company loosened its rules.

Starbucks is updating its dress code, limiting the amount of colors staff can wear with its green aprons starting on May 12.

Starbucks announced this week that their employees will implement a more specific dress code in order to make their signature green aprons pop.
