I dont doubt for a minute that there are clothes here made in China.
I dont buy em in the USA, and I dont buy em here, either.
I am a big fan of clothes from small argentine designers, who DO make clothes in argentina, and, which, of course, cost more than the ones from China. And can be high quality.
I wear the hell out of my black leather chaleco from Hermanos Estebecorena, for example. It was not cheap, although I would say it is cheaper than an equivalent US designer would charge for leather- but it has lasted me years already, and I expect it to last me many more.
How many throw away Chinese sweaters equals one good garment?
I am a bit of a bug about clothes- I have been making clothing myself since the 60's, have many friends who are designers, and generally pay more attention to clothes, and wear a wider variety of stuff, than most men- and I have found a variety of interesting, well made stuff in Buenos Aires.
Yep, there is plenty of cheap crap here, too.
but generally speaking, most people wouldnt wear what I wear, so I dont have advice on sports jackets or slacks.
