Anyhow, Paul... you said there is a Lee originals flagship store. I tried googling it, and the only sites that come up are Cultizm and Oki-Ni.
If you're buying mail order, check out aeroleatherclothing.com too.
The Edwin-made jeans were available at pretty reasonable prices on Rakuten last time I checked. Okini sales are definitely the best, though, and they do ship to the US.
