Dear Lee,
After checking out a number of costumer-links at CostumerManifesto.com, I settled on an Indian firm, UJNA Universal (Replicaters[sic].com), to make an Edwardian era army uniform. I initially thought I would find an antique uniform somewhere, but my frame is not exactly 19th century. Plus, if you buy vintage, the garment might be too fragile to wear and enjoy. Kyrila and Jim are right. If you plan on wearing the garment, have something custom made--preferably by a local costumer or dressmaker.
Best regards,
Doug
