An internet search on 'furrier Georgia' yields several results. However, some may no longer be in business. Macy's would not be my first thought for fine furs, despite the Chicago store having a whole section dedicated to furs. Do Macy's, NM, Sak's, Dior, Armani, etc. offer fur service, send the items out for service to a furrier, or do they offer in-house service?
I think it depends on how much you are willing to spend to get exactly what you want and what kind of service you think you will need in the future.
Thus, I suggest visiting several custom furriers and/or boutiques in person in order to compare their quality, customer service, and offered care services before committing to buy.
A custom furrier is the ultimate way to go when purchasing fine furs: not only will the item be custom fit to your body and designed specifically the way you would like it, and your name should be embroidered into the lining. They usually offer full service care and repair also. Some offer their customers fine fur consignment too.
