I used to live in Istanbul and I know of tourists donating all their clothes to shelters or just leaving them in their hotel room to make space for all the new cheap clothing they bought. Those were some crazy times.
Funny enough, many people from Turkey did the same when they visited the US in 2000s/2010s.
For the US/Canada it was the other way around. It wasn't uncommon for people from the neighboring Windsor Canada to go shopping in Detroit with cheap clothes on and return in new clothes with the cheap clothes from the morning discarded / donated.
I'm not sure if this has changed much or not (it is much easier to get an image of what a given car's passengers were wearing and compare it 8h later), but back in the 80s this was a viable tactic at dodging the purchase limits/customs declarations.
