I bought a pair of regular glasses from Chanel. After a few weeks the paint on the frame started crumbeling. The optician ordered a new pair, but after a couple of weeks the same thing happened with the new pair. He ordered a third pair, and again the same thing happened. I contacted Chanel Belgium via e-mail. They asked me to provide the proof of purchase and several pictures, which I sent them. It's been two months and I haven't heard anything back. That's 500 euro's wasted. I really wouldn't recommend buying their glasses.
