Olivia Molly Rogers leads the all-star arrivals for Styled By Bloom x Bianca and Bridgett at Quay in Sydney Harbour

Former Miss Universe Australia Olivia Molly Rogers wowed attendees as she led the arrivals for the launch of Styled By Bloom x Bianca and Bridgett in Sydney on Thursday.

The model, 31, looked extravagant in a black strapless mini dress from the label with bow shoulders.

Rogers had her brunette hair neatly styled with a park on the side, while the ends curled outwards.

Her makeup, styled by Kayla Perez, featured a natural brown eyeshadow, a nude, glossy lip and soft brows.

Rogers accessorized with drop earrings, a white clutch to match her nail polish and completed her look with a pair of sheer pumps with diamond detailing.

Rebel Wilson’s fiancée Ramona Agruma almost matched Olivia’s outfit with a black top with bow sleeves.

The fashion designer, 39, instead wore black trousers and strappy heels, while her blonde hair was tied in a bun.

Ramona wore silver jewelry and a bold red lip, which added a pop of color to her look.

Olivia and Ramona later posed together alongside Bianca Roccisano and Sarah Czarnuch.

Label co-founders Bianca and Bridgett Roccisano also rocked pieces from their own clothing brand, suiting up in black but showing off their unique sense of style in different designs.

The pair are also the co-founders of Booby Tape.

Bridgett looked dapper in a black blazer dress complete with black pumps, while Bianca wore a satin dress with a leg slit and a halter tie at the neck.

The piece also featured three flowers placed on the neckline.

Amy Castano was among the attendees who livened up the event, wearing a bright orange strapless crop top and a matching ruffled maxi skirt that hugged her athletic figure.

The top had cutouts and two flowers in the center of the panels.

Amy, who called time on her relationship with celebrity trainer Jono Castano in 2021, wore a black handbag and pumps, while she added a touch of silver with chunky hoop earrings, chain bracelets and rings.

The brunette had her hair cut into a ponytail and the bangs were left out to shape her face.

Big Brother star and model Ellie Gonsalves also wore an orange mini dress with a large bow at the front that was trimmed with diamonds.

The 33-year-old blonde bombshell opted for a bold and edgy makeup look, but stuck to neutral colors like a nude lip and brown eyeshadow.

Former Miss Universe Australia model Francesca Hung arrived in an orange strapless midi dress with ruffles and a flower on the left breast.

Hung, 29, accessorized with contrasting blue heels and leather handbag, while her brunette locks gave a fresh burst.

She posed next to Holly Kingston, who wore a strapless tan dress with pleats on the skirt.

Big Brother and Ninja Warrior star Katie Williams and her partner Georgia Hull arrived hand in hand.

Katie, 30, looked chic in knee-high black boots and a black blazer dress with white lapels.

Meanwhile, Gemma rocked a strapless tan dress with long sleeves and black heels.

The loved-up couple shared a sweet kiss for the cameras ahead of the event.

Other guests included Yummy Mummies star Iva Marra, former Miss Universe Australia and Survivor star Sarah Marschke, model Tegan Martin and MAFS star Domenica Calarco.
