It is very difficult to distinguish fakes from pictures, but I will try to help from my own knowledge: 1. Feedback is not the best way, half of the people do not have a clue what to look for. 2. Real Lacoste polos have devenlay tag on the bottom inside (right side) of the shirt. 3. Mother of Pearl Buttons (Some will be black, my purple shirt has black buttons). 4. Many people say the location of the gator is key but that is false. I bought 2 shirts at their outlet store and the gators were not in the same location. 5. View their other items. No person can have 30 Lacoste Polos and sell them for $10. 6. Ask for a UPC number, many of the fakes have the same generic UPC number. 7. Stick to sellers in America. I hope that this was helpful, just know that about 80% of Lacoste Polos in ebay are fake. If you will risk it, go for it and if you do get a fake, make sure to report it to ebay to help protect the Lacoste brand.
