Hi all!! I just had LASIK and have been in search for the perfect Chanel sunglasses to fit my wide face and "pinchable" cheeks. I like 4117B. Any ideas of where to buy reputably online (I've been scared of eBay because I naturally don't want fakes and I don't know of reputable sellers). Also, does anyone have any ideas on other Chanel sunnies that work for wider faces?? I need help! Thanks a million!
