Since replica (fake) bags are so popular in UAE do you consider it good for the economy and the buyer, and how does it reflect the original brand?

For environment good, don’t use or avoid plastic bags first.

We can’t stop the replica in this world, but you can advertisement that this particular bag available only at these retailers or dealers. So you can arrest the fake.

For some markets it will be good as most belong to low income level that need a brand identity (be it fake). However, that actually kills the real brand which might have a big impact on the mechanics that particular brand has on the market, and the loyal consumers to the original brand will likely feel less privileged.
