I like my clothes to be hard wearing, plain cut and American made, with union made as a plus. Also, I won't buy any more leather. After years of searching here and there, suffering poor quality or poor service, I have settled on a few vendors, including one whose parcel arrived today.
For pants, jeans, white socks, polo shirts and some t-shirts, I choose All American Clothes; I may have also gotten my last jacket there. For oxford shoes, I go with Pangea's "No Bull" house line, and for more fun ones (European made) I go with Vegetarian Shoes sold by MooShoes. For dress shirts, I get Canadian- and union-made Forsyths from hugestore.com, but may branch out to Pennsylvania- and union-made Gitman shirts that I can get through a men's store in Athens, Georgia, my college town. (And yes, they're expensive. Indeed, the only place I've seen them otherwise for sale in a store is in Paris.) But the as much as I think ethical sourcing is important, so to is taking care in choosing and maintaining clothes. Cheap clothes, badly chosen, are no bargain.
