At a uniform unveiling at Sydney's Clovelly Bay, breakdancer Jeff Dunne modelled the ensemble that will be worn along the River Seine for the opening of the multi-sports extravaganza on July 26 and was confident he could rock the look on the dancefloor.

Dunne will make history as the nation's first-ever Olympic Bboy after dancing his way to victory at the Oceania breaking championships last year.

His mother Rhondda had urged him to roll his chino shorts before the unveiling but the 16-year-old breakdancer was firm in his style.

"I love the dynamic moves - the spinning on your hands, on your head," Dunne said on Wednesday, 100 days out from the Paris Olympics.

"I could possibly do a few spins in them (the uniform)."

Designed by Sportscraft, the uniform aims to put Parisian fashion at the forefront while blending modern sporting elements.

The main attraction is a green blazer, double-breasted for women and single for men.

The blazer includes the Australian Olympian's oath on the inside jacket alongside the names of the country's 301 Summer Olympic champions throughout the jacket lining.

Underneath the blazer, athletes will have a choice of a sport-inspired tee or tank featuring gold and green ribbing, and a stone-coloured chino short or a green and gold ombre pleated skirt.

Canoeist Tom Green was among the athlete models and said seeing his name on the lining - just above his ribs - was surreal.

"It's really special, being able to see other athletes' names of all the Australian champions, alongside your own name," the Tokyo 2020 gold medallist said.

"Being able to point it out to family and friends that this is my spot on the jacket, it's really special."

The uniforms also feature Indigenous artwork by Olympic boxer Paul Fleming and Torres Strait Island artist David Bosun, used in the pocket square, scarf and with the Olympians' Oath on the blazer's inside lining.

To finish off the look, athletes will wear a revamped version of the iconic Volley Deuce shoes, which feature embossed Olympic logos, and subtle green and gold accents.
