Let me plug three vendors.
- The mystery US-made underwear manufacturer is Skiviez. (Search for USA.) Enjoy the ordinary briefs while they last, in limited sizes; I just ordered (closeout, sigh!) boxer briefs. They also sell fancy underpants, evidently for the gay and metrosexual market, also US made: these are more expensive so should be available in the future.
- I got a pair of slacks — dark olive, cotton, wrinkle-free — and walking shorts — olive drab, cotton — at ZebulonUSA, something of a one-stop-shop for US made clothes. Well made of sturdy cloth, comparable to department store prices. Alas, the slacks are old stock from Quantum Cotton; they’re now out of business. [2009. And ZebulonUSA is also out of business.]
- I’ve mentioned Pangea, a vegan clothing and accessories firm in the Maryland suburbs. (Locals and visitors: it is an easy walk from the Twinbrook Metro station.) I got my US-made, vegan (polyurethane and cotton fiber) dress shoes and belt there. Note, they don’t sell Chinese-made goods on principle.
Some days I come within an undershirt of having all my clothes made in the United States. It can be done with a little effort.
