Sexologist Chantelle Otten embraces her wild side alongside her partner Dylan Alcott as they lead celebrity arrivals at the Melbourne Fashion Festival.

Dylan Alcott and his sexologist girlfriend Chantelle Otten turned heads on Wednesday as they led celebrity arrivals at the Melbourne Fashion Festival.

Chantelle, 32, embraced her wild side in a daring leopard print bra, which showed off her slender figure, teamed with a matching skirt.

The redhead completed her outfit with black heels and accessorized it with a striking red designer clutch.

She accentuated her natural beauty with a radiant coat of makeup and couldn’t wipe the smile off her face as she posed alongside her Paralympic boyfriend.

Dylan, 33, looked every inch the rock star in an unbuttoned turquoise shirt, black T-shirt and matching pants.

The tennis champion completed his outfit with white sneakers and elegant sunglasses and a gold necklace gave a street touch to his look.

Dylan was all smiles as he posed alongside his beautiful girlfriend at the exclusive event held at the Royal Exhibition Building.

Also present was Robert Irwin, 20, who channeled his inner James Bond in a dapper tuxedo as he made his runway debut.

He looked like he was having the time of his life as he posed for photos on the red carpet alongside his I’m a Celebrity… Get Me Out of Here co-host Julia Morris, 55.

Julia looked absolutely radiant in a navy suit that included a low-cut navy blouse, adorned with the city skyline.

She paired the look with a pair of trendy sneakers and a charming smile.

Also attending the show were the likes of MasterChef Australia star Khanh Ong and his best friend, The Bachelor’s Matt Agnew.

According to a description of the event, Suit Up Runway shows how Australian designers have playfully reinvented the suit “in a variety of shapes, colors, fibers and patterns.”

“The looks feature stunning intricate embroidery, bold pieces and celebrate inspiring designers with incredible personal stories,” the description adds.
