How and where to get replicas of designer clothes made?

I purchase from Pakistani designers, but the fancier/heavier clothes are much more expensive. And I personally do not want to pay $150+ for an outfit I’m going to wear once maybe twice. I have seen some girls on TikTok get dupes made, but they never state where they get these replicas made from.

Does anyone know where and how I can get a replica made of a fancy designer outfit? I’m Pakistani-American and when I’m in Pakistan I stay in Islamabad. Which bazaar can I go to to get such clothes made? Please help a girl out 🥹🥹🥹🥹🥹

I’m attaching some pictures here to show what kind of clothes I want made. I don’t want to get super heavy clothes or simple clothes made. Something that’s fancy, but not too fancy.
