William & Kate Launch The Calgary Stampede

William & Kate have arrived at the final stop of their nine-day tour of Canada -- a reception celebrating the world-famous Calgary Stampede, a rodeo festival and show.

The couple arrived  on an eye-catching 1912 stage coach amid a tumultuous welcome and were suitably attired for the event wearing white "ten gallon" hats they had been presented with earlier in the day, and finishing off the look with cowboy shirts and boots, and jeans.

Specifically, Kate wore an Alice by Temperly blouse, Goldsign jeans and her own cowboy boots.

The blouse is the 'Armonia Blouse' ($255) from the Alice by Temperley Resort 2012 collection. The description is as follows 'White and blue feminine blouse features embroidery bib and collar with scalloped detailing and puff sleeves .'

•White semi-sheer cotton

•Purple and navy embroidery, ruffled high neck and bib, buttoned cuffs

•Button fastenings through front

•100% cotton

William & Kate's hats are made by the Smithbilt Hat company www.smithbilthats.com

The company produces three styles of white hat. The New West made of glazed canvas goes for $18.50, and Smithbilt recommends it for large groups who need to be Stampedeready. The "truly gorgeous" Old West model is made of Merino wool and priced at $72.50, precisely sized to the wearer. The Cadillac of Smithbilt hats is the Wild West, an "Official White Hat" made of 100 per cent rabbit fur and ringing in at $199.99.

According to the company's history, Calgary's iconic white hat was born in 1946, when Morris Shumiatchew of Smithbilt Hats introduced a pure white cowboy hat made of imported Russian felt.

Two years later, the hats became a de facto symbol of the city when the Calgary Stampeders competed for the Grey Cup and 250 raucous fans wearing Smithbilt hats descended on Toronto to support their team, bringing with them a chuckwagon, 12 horses and a hat for the Toronto mayor.

When Don MacKay, a man Smithbilt describes as a "born promoter," became Calgary mayor in 1950, he started presenting the hats to prominent visitors to the city.
