Delta has officially unveiled its new uniforms designed by Zac Posen.

The company says the new line, which will be worn by more than 60,000 of the airline’s frontline employees, “fuses together bold color palettes and classic styles, while paying homage to the heritage and iconic design from decades past to elevate the look and brand of Delta employees.”

“We wanted Delta employees to look glamorous on the job without sacrificing functionality and style,” said Posen. “I worked alongside employees to understand how they interact with the clothes they wear and developed a look that empowers and excites, because we want Delta’s global workforce to exude the confidence and thoughtfulness that reflects the airline’s brand.”

Delta will begin by having 1,000 employees wear-test the uniforms in December and early 2017.

The full roll-out will begin worldwide in the first quarter of 2018.

“The world’s best employees deserve the best uniforms and this new collection is classically influenced, yet modern,” said Ed Bastian, Delta’s CEO. “Zac and the Delta team worked closely with our people to create timeless and fashionable pieces that reflect the thoughtful and innovative spirit of Delta.”
