To check if DKNY sunglasses are genuine, follow these steps to ensure authenticity. First, inspect the logo on the DKNY shades. Authentic DKNY sunglasses will have the DKNY or Donna Karan New York sunglasses logo clearly and evenly printed on the frame. The logo should be sharp, without any signs of distortion or blurry text, which can be common in counterfeit models. Next, evaluate the build quality of the sunglasses. Genuine DKNY sunglasses are crafted with high-quality materials like acetate and metal alloys, ensuring that the frame feels solid and well-made. The temples (arms) of authentic DKNY sunglasses should open and close smoothly, and there should be no loose hinges or rough edges. The lenses should also be of high quality, providing clear vision with no distortion, and offering UV protection. Examine the packaging as well. Original Donna Karan New York sunglasses typically come with a branded case, a cleaning cloth, and product tags or booklets, all featuring the same authentic logo. The model number on the frame should match the one on the box or the product page from the official website, ensuring the product is genuine.
