There are a few things you can look for to spot fake.
First, check the quality of the materials and construction.
Porsche Design sunglasses are made with high-quality materials and craftsmanship, so if the sunglasses you’re looking at seem cheaply made, they’re probably fake.
Next, take a look at the logo.
The Porsche Design logo should be embossed on the lens or printed in white on the temple.
If the logo is missing or seems to be of poor quality, it’s likely that the sunglasses are fake. Finally, check the price.
Their price is higher than other brands, so if you find a pair that’s being sold for a fraction of the cost, they’re probably not real.
If you’re still not sure, you can always buy from an authorized retailer to be sure you’re getting the real thing.
