SHANGHAI -

A Chinese airline is causing a stir after changing up its classic flight attendant outfits.

Spring Airlines is dressing its attendants as butlers and maids, according to Shanghai Daily.

The new promotion is attracting criticism in the communist country.

There are concerns that the costumes pose a safety risk.  Some say  flight attendants having their hair down, instead of pulled back, could pose a problem.

An airlines spokesman said the pilots would also wear an outfit featuring a long black apron as well as a tie, the paper reports.

The Shanghai-based budget airline is the first to have its crew members dressed as maids and butlers.
