Offering new products in your lineup often means a sign of growth for your company. Ronnie Fieg has done just that by slowly building up his empire. From footwear to a clothing collection, his portfolio will now include an eyewear collaboration with NY-based eyewear shop, Tina Catherine. The collaboration introduces the Tina Catherine x KITH NYC Chelsea sunglasses. The specs are handmade in Japan and set to drop July 13. More information on price and location are yet to come, but you can peep the video above for a preview. [ronniefieg]
