"It's the image that you want to project to the world, it's who it is you want to project yourself to be.
"We all want to be comfortable in our home, but we want to look good. If I'm wearing trackpants in my house they're cute trackpants, they're still fashionable. I walk by mirrors, we want to look good, I do at least."
Not surprisingly, the most memorable Kiwi on Kotsiopoulos' radar is Grammy winner Lorde.
"She seems very outspoken and speaks her mind and doesn't say stupid things, which is great," he said.
He said the teen's "grungy, moody" style reminded him of fictional character Beetlejuice (which he watched on the plane).
"For someone to be that young and not that famous, it's smart to have a look," he said.
"You just associate her with having that big, black curly hair.
"It's like, okay, that's Lorde, just let it simmer in the Zeitgeist for a while. Let people know who you are. You want to be memorable."
Kotsiopoulos mingled with local media and celebs at a waterfront party last night and will jet off to Melbourne today for fashion week before heading to Sydney.
