Effective immediately, a range of shirt colors beyond solid black and white are welcome, including gray, navy, dark denim and brown, including patterns.

 Some partners (employees) have already been wearing clothing that fits the new dress code guidelines. “It just makes it so much easier.
– Just like a Starbucks customer can match her perc to her personality via a customized coffee, company baristas can now also "shine as individuals" thanks to the java giant's updated dress code. Per a company release posted Monday, baristas are now allowed to diverge somewhat from the black, white, and khaki attire that's been the Starbucks standard. Although the green aprons aren't going anywhere, baristas can now wear navy, brown, and gray clothing underneath, as long as it presents a "clean, neat, and professional appearance." Wild hair hues, previously forbidden, are also now welcome—though it has to be permanent or semi-permanent color and can't have glitter or spray in it for health reasons, Fortune notes—and employees can top off their tresses with beanies, fedoras, or other "suitable" headwear within the same color approved color scheme. The new dress designation, which will take effect in all stores in the US and Canada, offers "more of a hipster, average Joe coffee shop feel," US News reports—and it notes the chain could harness that feel to "broaden its fast casual, basic appeal." Business Insider notes that employees had long asked for similar concessions, especially regarding hair color, including via a petition with nearly 15,000 signatures that says, "Starbucks is [a] place where partners are unique and should be able to show their true selves." The code is expected to affect some 150,000 workers in the US. "This new dress code is what partners have in their closets," a Starbucks store manager in Manhattan says in the release. "It just makes it so much easier." Check out the company's new acceptable color palette here. (Starbucks also recently announced it will raise workers' wages.)
