My dad was sent to some developing country on a business trip. While there he bought a tailor made suit for fairly cheap - he wore that suit every day for several decades. It was more comfortable than the jeans/t-shirt most people wear.

I don't remember which country, but I'm pretty sure we would call it a developed country today so probably not worth going there today. Still if you get an opportunity to travel you can find tailors in some countries that do great work for cheap. (and also rip offs that do terrible work for high prices)
