For the fiancées of ambitious founders, there's a new metric of wealth for their future spouses to live up to: "I don't want you to sell unless you can make Miyake money."

But Jyri Engeström just announced that he and his bride-to-be Ulla-Maaria Mutanen are in Tokyo, getting her wedding dress personally fitted by famed designer Issey Miyake. (Girls, note this: She proposed to him.)
