Has anyone ever copied your perfume???

OK, so if its copied once, u r flattered. BUT...

One of my relatives in pakistan copied mine, then another copied it, and even a 3rd copied it too.

So next time i went, i changed my perfume, soon after, lo and behold, the same scent soon appeared on 2 others dressing table.

Should i wear a really cheap and nasty perfume next time i go there, and c if they copy it? Any suggestions???
