We have many seller here in Malaysia who sells imitation perfume BUT they claim it's original. Some of them they don't even know that they are selling fake perfume.
Here some example of imitation perfume coming from Dubai/China.
(Check out alibaba.com - you will notice that those suppler from China don't dare to mention "GENUINE/ORIGINAL", or they don't mention the exact name of the perfume like Chanel Coco Mademoiselle is > CC Mademoiselle)
