6 designers shaking up fashion

Frank & Oak doesn't just design and sell trendy threads for the millennial man, they're constantly releasing content -- from articles to digital videos -- to boost their brand.

They roll out 75 new menswear products a month -- most of which are only available for about two months.

The "limited edition" idea builds on the company's "members only" model, which 1.5 million users have signed on to. Membership is free and enables Frank & Oak to curate products according to customer preferences (taken from a brief survey upon sign-up).

Co-founder Ethan Song describes their style as American classics with a European flair. And they're competitively priced -- somewhere between J.Crew and the Gap (GPS), according to Song.

The Montreal-based startup (which also has a brick-and-mortar store in Montreal) captured a $15 million round of funding last week and announced plans to open an office in New York City.
