Say what you want about USA, but it's the only place in the world where I've been consistently able to find clothes that fits tall people. I'm 187 cm (~6'2").
For a year now I've been hunting for jeans I can use. I have a single pair of 34" length left, and those are technically a little short.
I was on a trip to the US once with a fellow uni student of 207 cm (~6'9"). We hunted for clothes there, and found lots.
Just got a pair of jeans in the mail that reach the floor! 😁
