The Calvin klein 175S 521 sunglasses, with its black frame and iconic round silhouette, is a rare vintage sunglasses find for collectors.

One of the most underrated things about vintage Calvin Klein sunglasses is their versatility. Whether you’re in a hoodie, a leather jacket, or a tailored suit, they just work. That’s because the designs were rooted in timeless proportions—shapes and fits that compliment almost anyone’s face. And they’re lightweight, too, making them as comfortable as they are stylish.
