The new designs use a colour palette pairing navy blue with a softer orange, which Smart says was inspired by the sunset through a plane window.

“Embarking on the creative journey to design uniforms for Jetstar was a fabulous adventure that began with a deep dive into the airline’s vision and core themes of fun, unity, holidays and affordable travel,” she said.

“We focused on the anticipation of the destination, the excitement of looking at a map, dreaming about the possibilities and the thrill of arriving at a chosen destination.

“The evolution from black to a dynamic blue and orange palette reflects Jetstar’s transformative journey over the past two decades, while the looks were intended to feel like pieces one might instinctively pack for a holiday, whether it’s a linen jacket and cotton chinos, a shirt dress, or a smart polo.”

Pilots are moving from a black suit to navy blue, with redesigned epaulettes and the option to wear a neck scarf, while cabin crew and airport staff will have options of blue or orange blazers, as well as shirt dresses, tailored skirts, tapered fit trousers, polos and overcoats.

Existing Jetstar uniforms will be disposed of through a partnership with recycling company BlockTexx.

According to Jetstar CEO Stephanie Tully, the new uniforms give crew “more freedom to choose what they would like to wear”.

“We’ve listened to our people and together wanted to create a uniform that reflects how far we have come as we move into our third decade of operation,” she said.

“Sustainability has been an important part of the process, including ensuring that Jetstar’s current uniforms are repurposed into new products.

“Our new look uniform comes as we celebrate our 20th birthday in May and adds to our investment in new aircraft, new routes, and new cabins for our international widebody fleet to help customers fly to more places more often for less.”

Qantas last year updated its dress code guidance to remove gender-specific uniform rules on its mainline services, allowing all employees, regardless of gender, to wear flat shoes, long hair in a ponytail or bun, makeup, and the same jewellery including watches.
