Uhhhhh... Ksubi? Your 09/10 eyewear collection may be called "Book Club," but it looks like your Bellatrix sunglasses are straight plagiarized from Chanel 5018s.
That said, the Bellatrix, shown above, will only set you back $289. Good luck finding the real deal 5018s (as seen below on an Olsen) on eBay.
Those really looking for a deal, however, should just go with the $10 version from girlprops.com.
