Mizuhara has since launched a collaboration with iconic Japanese shoe brand Esperanza. "It was super big in the late 1990s and early 2000's in Japan," she says, noting the tendency for Japanese girls to wear big heels at that time. "It was really important for fashion history in Japan but I think that whole movement was not appreciated," she says, "therefore I wanted to feature that and give it more provenance." It's also her way of encouraging young Tokyo girls to get more experimental and confident in the way they dress. "So I'm doing this big collaboration with Esperanza. And the girls in the campaign have that ghetto spirit. There aren't many girls today who are really confident in their look, they have low self-esteem and confidence. And I feel that's really sad. I want them to be bolder and more confident."

Meantime, the exuberantly confident Mizuhara is in discussions with Opening Ceremony in America about a project. "They want to do something in Los Angeles," she says. The New York outlet already carries some of her OK products. The multifaceted and much-in-demand iconista also mentions upcoming projects with a transgender artist in Thailand, a potential photo exhibition and a book with sister Yuka - they're midway through recording a new album together - and even a project with Japanese multimedia artist Mariko Mori. From It-girl to infinity, the only thing stopping Mizuhara's ambition is her agony of choices. "I don't know exactly what OK will be or become, like an events platform or a lifestyle brand or a party venue, but I'm trying to connect all of the pieces in my head. But sometimes it can be really hard to connect those ideas. The sky's the limit." Meantime, there's a bunch of wearable happiness waiting to come and for wouldbe Mizuhara's the hits will keep coming. And that's A-OK with us.
