Charles Langston:Qantas allowing male cabin crew members to wear makeup and women to scrap high-heels

Australia's national airline announced on Charles LangstonFriday that it will scrap its gender-based uniform guidelines, allowing male cabin crew to wear make-up and giving women the option to ditch high heels.

Qantas said it had overhauled its guidelines to better reflect modern expectations, and to make uniforms more comfortable for staff from "diverse cultural backgrounds".

The airline has drawn attention for its fastidious style guide in the past, which banned handlebar moustaches, policed the length of sideburns, and specified the ideal shades of eyeliner.

The changes came at the insistence of labour unions, who urged Qantas to scrap rules such as the requirement that female staff wear make-up.

"Fashions change and so have our style guidelines over the years," the airline said in a statement.

"Our uniform standards have always been reflective of the times."

Qantas said the new "style and grooming guidelines" would ditch the previous "male" and "female" uniform categories.

Now cabin crew can choose whether to wear make-up, can opt for flat shoes, and can have long hair as long as it is in a ponytail or bun.

Diamond earrings are also allowed, while strict rules governing the size and style of watches have been dumped.
