Sometimes a deal seems like it's too good to be true, and in the case of Armani Exchange sunglasses, that's often the case. Armani Exchange is the less-expensive offshoot of the Armani brand, but their sunglasses can still sell for a pretty penny. This gives way to countless knock-off items designed to look authentic, despite being made and sold for much less. When eyeing AX sunglasses, closely examine the product to make sure you're getting the real deal.
Research the real thing. Before you set out for your sunglasses, do some comparison shopping online. Browse the sunglasses collection on the AX website, or on a site like Macy's or Nordstroms. This way, you'll know exactly what's being sold this season and what they look like.
Check the price. Real Armani Exchange sunglasses start at around £39, unless you pick up a pair at an AX outlet or discount rack. If your pair costs significantly less than that---and you're not buying it at a reputable retail store---that's a warning sign.
Inspect the glasses. If they're real, the frames should feel sturdy. The wraparound bands on the side should fold in and out smoothly, and the connecting spring should not squeak or be obtrusive. The AX logo should be crisp and embedded into the side---not just tacked on. The lens should look clear and feel delicate. Most important, the lens should be properly tinted. Most Armani Exchange sunglasses have a subtle tint that lessens as it moves down the lens: The top part should be slightly darker than the bottom part. A common tip-off of an imposter is that those lens are entirely the same tint.
Examine the accessories. Besides a certificate of authenticity, real Armani Exchange sunglasses should generally come with two things: a case and a cleaning cloth. Both should sport a crisp, clear Armani logo. If the logo looks chipped, glued on or otherwise inauthentic, they're likely fake.
Sites like eBay often sell designer sunglasses. Before you buy, check the seller's feedback---what have previous buyers said about the authenticity of their goods? Legitimate sellers should be able to provide a certificate of authenticity for the product.
