I would like to purchase or trade for a preferably Confederate Colonel's jacket but will consider any. ( Doesn't need to be authentic I would prefer a replica like something a reenactor would wear)
For new items, I would suggest checking out some of the respected sutler companies, such as C & D Jarnagin (located in Corinth, Mississippi), Quartermaster Shop (Kimball, Michigan).
You can find used reenactment uniforms on ebay, but it may take a while to find one in your size, and that falls in line with what you are looking for. The Pakistan and India made uniforms are all over ebay, but as another member already mentioned, these are not recommended due to comfort, authenticity factor. For some reason, on every one of these that I have seen, the cuffs on the Confederate models are all wrong. (There is too much width to them).
I have not dealt with Quartermaster Shop myself, but have seen them recommended in other forums for quality and authenticity. I have ordered items from C & D Jarnagin, and found them to be well made and decently priced. (A jean cloth C.S. sackcoat, trousers, etc.).
There are other U.S. based sutlers that offer quality products, along with some that are not as good.
For quality footwear, check out Missouri Boot and Shoe Company ( Neosho, Missouri). They also offer belts, cartridge boxes, etc.
