Pretty much all clothing in the US is imported. Mainly from China but we also have imported goods from India, Vietnam, Mexico, Bangladesh, etc.
It is a shame people ain't making clothing in America anymore and most of our products are coming from China.
I find overall the best quality work seems to come from Vietnam. I have a few sweatshirts that have held up for years and still look and feel new. The fabric and sewing job they do there seems to be a level above China.
I also have a few items from India that are good, especially compared to China. It seems like the quality coming out there is falling off big time and I am noticing this at stores like Old Navy. Used to get my socks from them but I swear the same socks I am always getting are thinner and tighter, and they feel like they won't last but a few wears. The other ones I got previous just feel some much better. Same make, brand, etc. both made in China. Something is up.
