Canadian fashion designers David Dixon and Joeffer Caoc see a sexy, modern Kate Middleton walking down the aisle and into England's history books on her wedding day.

The mystery surrounding Kate Middleton's wedding dress continues to build.

This weekend, the world buzzed with the news that Sarah Burton, the creative director for the house of Alexander McQueen, had been hired to make Middleton's wedding gown.

That confirmation was quickly dismissed by McQueen representatives.

But Canadian designers David Dixon and Joeffer Caoc have their own thoughts on what 29-year-old Middleton should wear for her big march down the aisle on April 29.

"She's very modern. She's very youthful. And she's got a great figure," Caoc told Canada AM today.

To flaunt those attributes, Caoc unveiled his own design for Middleton's wedding gown today.

Caoc's concept featured a sleek, off-the-shoulder bodice, an A-line skirt in white satin and a Tiffany-blue organza bow at the waist.

"It's demure-sexy," said Caoc -- just like the future Queen of England.

"The blue is to reflect her sapphire ring," Caoc added.

"She's still young. We don't want to dress her old," said Dixon.

To showcase Middleton's sleek physique, Dixon has created a dramatic, fitted gown concept embellished by handmade silk flowers and butterfly crystals sewn onto Chantilly lace.

Those grand embellishments have been included for royal watchers that "will want to be wowed." Dixon said.

The grand detailing is also right for the times, said Dixon.

The world is ready for a little escapism and "just a little more decadence," Dixon said, especially given today's news headlines.

That decadence will also be reflected in the jewels that Middleton wears on her wedding day.

According to royal watcher Hillary Brown, Middleton's tiara will likely be that "something borrowed" item for her big day.

"The Queen has about eight tiaras. The jewel pool is valued at $50 million," Brown told Canada AM today.

Middleton's pick should come from that collection. It will also be returned to the Windsor family collection upon her death.

But like her royal jewels, Middleton's dress and the designer who creates it should bear some historical connection to England.

"She'll choose someone British," said Dixon.

"I don't think (John) Galliano so much," he said.

The British designer may have topped Middleton's picks a few months ago. But Galliano's recent dismissal from the house of Christian Dior has changed all that.

Galliano made headlines for allegedly making racist comments to a couple in a café. Those allegations forced Dior fire Galliano from his prestigious post.

Given the strength of Britain's fashion design pool, Middleton's wedding dress pick could still leave some room for surprises.

Despite McQueen's representatives denying the reports, Dixon made this prediction: "I think she might step out of the box and go with the house of McQueen."
