There's a reason why Alex Perry has been labelled Australia's boss of the ball gown, king of corsets and sultan of sequins. The renowned coutourier has successfully tapped into the Aussie girl's ultimate princess fantasies, and we can't get enough of it.

Never one to shy from a grand entrance, the red carpet regular debuted his bright and bold `Cuban Princess' collection on Wednesday night as part of L'Oreal Melbourne Fashion Festival. His first collection launching Melbourne runway show took place at the grand Royal Exhibition Building.

The historic site's swooping ceilings and gilded columns set a majestic mood and offered a colossal runway to accommodate his extensive star-studded front row which included the glamorous international model Jessica Gomes, former Miss Universe Australia Rachael Finch, L'Oreal ambassador and Ground Hog Day actress, Andie McDowell and festival face Melissa George.

But all eyes were on Alex's `ultimate Perry girl' Megan Gale who turned up the heat when she opened the Latina-inspired show with her fierce strut and sultry stare.

“After my wife Mary, she is my ultimate Perry girl, I love her, she's a great friend,” he said.

“Somebody asked me earlier who is your favourite celebrity in the world to dress and I said Megan, she's the bomb."

“She's the quintessential, the girl that you look at and you just go (wow), women love her, men love her, she's just that gorgeous. She is a glamazon!”

The temperatures soared as Gale led charge with a string of Perry girls sashaying behind her wearing sassy party frocks in bright colour-blocking that fused tamale red silk trimmed with curacao blue, paprika with blood orange tones and nude with lime that Perry says is both "grounding but with an amazing splash of colour”.

And all in Perry's new and fresh silhouette of tight racer-back tops with ball gown skirts in a stunning silk georgette – styles that are sure to get the cotillion-crowd's hearts racing.

“I love women, I love their shape, I just look at the things that for me are quintessentially beautiful about a woman, the waist, the bustline, the legs. You know I just I love doing things that show that,” he said.

“And even if they don't, I mean there were a couple of dresses in this collection that were formless, but you still got to see a woman's shape underneath it. You got to see her shoulders, her collarbones. I love things that are hourglass and celebrate how a woman looks.”

While Perry is renowned for his frills, flounce and signature sequins, this outing he said it was time to scale back on the embellishment and hone in on impeccable tailoring.

“Not that much (sequin), I went easy on the beading this time and it was block beading rather than things that were too intricate,” he said.

“And there was a lot of colour because I had not done colour for a while.

“It was about simple-as shapes in the bodices, like little racing top singlets with ball skirts just to make it a bit fresher and a little more ready-to-wear in that sense, but just to feel a bit younger and a little bit more, you know, not the word tropical, but I just wanted to feel young and fresh."

“But having said that, there's stuff in there for women of all ages.”

The show finale featured long stiffened evening skirts slashed high up the thigh to reveal toned bronzed pins, but with the legs on show Perry countered it with high necklines on bodices; origami-style halterneck tops.

Despite the obvious cultural references to the South America, Perry admits he didn't travel to the region to source inspiration this time.

“I either have been to the countries I get inspiration from, or they're places I want to go to,” he said.

“The suiting was derivative of men's Cuban suits which were white and sharp and beautiful, and then there was that beautiful floral that I had printed that was black background, with the floral pattern, and then it was the colour.”

Never one to sit still for long, Perry flies back to Sydney on Saturday to start on his winter collection.
