New York Fashion Week is only a week away but who's counting? Um, we are.

And we have more news to report on the nail polish front, which is shaping up to be a major accessory for fall (hello, Chanel Khaki).

Zac Posen has chosen OPI Nail Lacquers as his official partner to create the nail looks for his Z Spoke by Zac Posen runway show.

"Given that OPI is the leading nail lacquer in the world, we couldn't resist working with their gorgeous array of colors," said Posen. "OPI is a noted fashion accessory in itself and will add the perfect touch to this year's Z Spoke collection."

"When Zac reached out to us, of course, we jumped at the opportunity. We'll have OPI technicians working on his show in New York and in Paris," Suzi Weiss-Fischmann, OPI Executive VP & Artistic Director told StyleList.

"OPI worked on the Marc Jacobs and Marc by Marc Jacobs shows last season. And in addition to Posen, we will have technicians styling nails at Rebecca Taylor, Charlotte Ronson, BCBG, and Max Azria," added Weiss-Fischmann.

Of course StyleList had to ask Weiss-Fischmann for an exclusive on which colors Posen's models will be wearing: "Zac loves deep greens, blues and oranges, He just really loves bright colors on nails and designs. We are figuring out how to accomplish all of that on 45 models. He wants toes to be very muted."

Will greige be among the muted shades?
