Fashion has a dark side - it's not all runways and lipstick and fishtail gowns.
I don't believe in one ideal beauty.
I have to bring my A-Game 24/7, between creating, draping, and overseeing a myriad of different brands.
I eat everything, but I moderate; I try to be semiconscious. I don't eat pasta every day, although people who follow my Instagram think I do.
The most significant pieces for me are the ones that come from my drapings. It's emotional because they are created by my hand and then become a collaborative process in the atelier.
Sometimes, late at night on the set of 'Project Runway,' I've been known to pop an interpretive dance.
One of my fantasies is to produce 'Auntie Mame' as a play.
For me, I'll unwind at the end of the day by soaking in Epsom salts. It's the routine I prefer for coming down after crazy days.
If you're entering into fashion in an original way, you have to know your craft, and you have to know your history. You have to be obsessively dedicated. You have to be relentless about making it happen. It doesn't take a bank. It takes passion, love, timing, and luck.
Creative burnout and physical burnout is real. I mean, there are moments when I get home - after overseeing, you know, almost 16 collections a year - where I can't move.
The first time I went to the Met Ball, I was 16. I was an intern there and saved up to buy a staff ticket to the party. That was my favorite experience going. It wasn't the red carpet; it was the experience of being there for the first time.
Obviously, I like very beautiful food, because I think as delicious as food has to taste, it also has to look very beautiful - the process of presentation is very important.
I went through the workroom at Central Saint Martins in London, which is the most competitive workroom of a design school in the world. Very high creativity, very conceptual, very international, age-diverse and cutthroat - people who have master degrees reapplying into a foundation there is just wild to me to launch their careers.
To me, being in fashion is about your work, not about facilitating a lifestyle.
I'm definitely planning ahead for a brand that spans the universe - a Zac Posen universe.
When you make and drape clothing, the scissors are your tool. What can I say about them? They're my babies. And you have to take care of them correctly. You have to have them sharpened, and you can't use them for any other material.
I was very interested in theatre, so my first love of fashion comes from costume, and I think that's pretty clear within my work and the level of theatricality.
There's not one major greatest influence on my career. It would be film and great artists and great imagineers - Jim Henson, Walt Disney, Charlie Chaplin, people who understand the joy of the imagination.
I garden in my Brooks Brothers pajamas and straw hat.
I am a compulsive and concise shopper.
