"Breakthrough ideas often come from the least expected sources.
For Daniel Friedman, the flash came from a woman named Rachel Tutera. Mr. Friedman makes custom men’s suits, mostly for corporate clients in his end of Park Slope, Brooklyn.
Ms. Tutera runs a blog called The Handsome Butch. When she wrote to him last year, seeking a sales job, she had a proposition: Why couldn’t Mr. Friedman, with his expertise in men’s suits, make them for women like her — not women’s suits, but the same gear he was making for guys, with the same masculine profile, but fitted to women’s bodies? It was a question he had never considered."
