When famed fashion designer Zac Posen rolled out his new line of Delta Air Lines uniforms in May 2018, the five different color schemes were seen as a radical departure from the airline’s 30-year-old palate of red and blue. But two flight attendants are only seeing red over their new ensembles, and they’re suing.

Gwyneth Gilbert and Monica DeCrescentis have filed a proposed class action against retailer Lands’ End, which made the uniforms. Their lawsuit contends that the clothing causes skin rashes, headaches and other issues, reports the Atlanta Journal-Constitution. Neither Delta nor Posen are named in the suit.
