Authentic! Bought from the Hamptons NY Prada store (receipt attached)! Prada Gold frame & Anthracite Gray Lens triangle Prada logo sunglasses. Lens-nose-temple measurements: 57-18-140 mm. Adjustable nose pads. 100% UVA/UVB protection. Lightly worn, great condition with the slightest little scratches on lens, could barely get pictures (zoomed in above). These are so luxurious! And I’m a lunatic about fit, they are SO comfortable and can be worn all day long with no pain on the ears or temples. Perfect for summer into fall. Looks amazing with gold jewelry.
