1. one way to tell if the bag is real or fake is the background. if the picture of the bag looks like the seller took it themself then it is most likely real, if the background looks like a pro took it. hate to break it to you but your getting ripped off.

2. another tip is if the bag is lighter and or darker than it is in real life

it is not  real.

3. if the bags handles are wrapped in plastic the bag is not real. every chanel bag i have ever gotten has been wrapped in tissue paper.

Those are a few tips to help you decide if your chanel bag is real.
