Delta people showed off the airline’s new uniforms Tuesday at an exclusive event in Atlanta. A video shows highlights from the runway as well as reactions from acclaimed fashion designer Zac Posen, Delta leaders and employees.

“The energy in the room was amazing. Everyone was so excited to see what Zac did,” one Delta uniform model said about the event.

“It started to build backstage,” Posen said. “For me, this was kind of a life changing experience.”

Posen partnered directly with Delta employees from nearly every work group to design the new collection over the last 18 months, developing a functional wardrobe fit for Delta's diverse employee group and the environments where they work. Employees influenced the design and final selection of each uniform piece.
