HAIDA GWAII, B.C. -- Toronto-based fashion label Smythe has become an apparent favourite of the Duchess of Cambridge.

Kate arrived at the remote archipelago Haida Gwaii on Friday dressed in an army green "Duchess" blazer from Smythe's fall collection.

While it was the first glimpse of Kate in this particular blazer, a navy blue version has been a staple in her wardrobe since the 2011 Canadian royal tour.

Smythe co-founders Andrea Lenczner and Christie Smythe say they are thrilled to be included Kate's wardrobe yet again.

An appearance of the duchess wearing particular brand can mean big business for designers.

Barely a day after Kate wore a grey alpaca coat by Toronto label Sentaler, the item sold out online along with many other garments by the designer as orders poured in from all over the world.

The influence the duchess can have on the fashion industry by inspiring both royal watchers and fashion enthusiasts to replicate her look has been dubbed the "Kate effect."

During Prince William and Kate's eight-day tour of British Columbia and Yukon, fans have closely tracked every outfit the duchess has worn.

Bojana Sentaler said Kate's appearance in her label's grey coat on Wednesday brought her brand instant global awareness.

Sentaler said she hopes the attention will help her expand into international markets.

Smythe's made-in-Canada apparel has already gained celebrity attention around the globe, but is founders say they are delighted to see Kate continuing to choose their garments.

"We design with a woman like Kate Middleton in mind: tailored and effortlessly chic," they said in a statement.
