Could Meghan Markle's wedding dress look like this?

There's really only one wedding dress that counts this year — the one Meghan Markle will be wearing on May 19th at St George's Chapel, Windsor. The British couture house, Ralph & Russo must be the front runner to design the gown.

For starters, it created the rather daring sexy mini dress sheer-bodiced 56,000 confection that Meghan wore lacy sexy mini dress to pose for her engagement pictures.

Secondly, it's the designer of choice for Americans looking to impress royalty: Angelina Jolie wore a very demure powder grey/blue tailored Ralph & Russo suit to collect an honorary damehood from the Queen (who was wearing apricot).

And thirdly, this season's couture show, on a very rainy Monday in Paris, will have done much to bolster its claims to the join the illustrious roll call of Alexander McQueen (the Duchess of Cambridge), Robinson Valentine (the Duchess of Cornwall), the Emmanuels (Princess Diana) and co.

Tamara Ralph, long sleeve midi dress the house's creative director, cast one Camila Coelho to wear the wedding gown that amid drumrolls, drama and an explosion of flashbulbs, closed the show.

Far from a lanky model, the Brazilian social-media star is only 5ft 3in — and if she could carry off this particular look, how much better could Meghan Markle at 5ft 6in?

The dress itself was absolutely gigantic, fully 12ft across and with a train and veil that stretched back easily twice as far.

The draped bodice and skirt, the show notes tell me, were embroidered with 3D Swarovski jewelled leaves, pearlescent micro-beads and silk floss flowers, but you couldn't spot that on the catwalk, all you saw was a great swirl of silk, sparkle and lace. It was the meringue to end all meringues.

If Meghan baulks at this gigantic number, there were plenty of other options during the long sleeve midi dress show that, if you merely converted them from acid green or scarlet or peach to white would make perfectly acceptable wedding outfits.

Ralph & Russo is the only British house allowed by the august Chambre Syndicale de la Haute Couture to show during Paris couture and all its dresses are made by hand in an atelier bigger than Chanel's.

This means its beading, fringing, embroidery and application of feathers are really second to none. She'd look knockout in many of them — but I do hope she goes for the biggie.
