Luxury eyewear designer Illesteva is known for their awesome collaborations with Opening Ceremony,Band Of Outsiders, and Corto Moltedo. And now they've just announced another collab coming out this month. For the first time in his entire career, design icon Zac Posen has decided to delve into the sunglass world, and he personally chose Illestevato make the jump. The masterminds behind the shades, Daniel Silberman and Jus Ske, are big ZP fans right back and just couldn't turn down the offer. (Who could say no to Zac Posen?) For his first-ever eyewear collection, Posen includes cat-eye frames and '60s inspiration in five different color stories — yellow, clear and tortoise, green, brown, and leopard — all handmade in Italy and France. They'll be available atColette, Opening Ceremony, and of course,Ilesteva.com, this month, just in time for summah-summah sunshine.
