One of New Zealand's most noted designers, Walker exhibited her first collection of products in 1998 and now holds shows each season at the New York Fashion Week.

She has expanded from designing womenswear to sunglasses, jewelry and shoes.

Her products have been used by Western style icons such as Charlize Theron, Anne Hathaway, Alexa Chung and Chinese actresses Zhou Xun and Fan Bingbing.

"When you see somebody, your eyes meet their eyes. That's how we connect as human beings. That's one reason why sunglasses are such an important part of people's looks. It can be the last thing that you put on, but can totally change your whole outfit," Walker says.
