My favorite Southern bow tie companies are:
R. Hanauer (located in Rock Hill, South Carolina) R. Hanauer
Hanauer produces luxury handmade bow ties from materials woven in the US and England.
High Cotton (North Carolina) High Cotton
A great company that specializes in high quality bow ties (especially madras and seersucker).
The Cordial Churchman (Rock Hill, South Carolina) The Cordial Churchman
From their website: "It all started when owner, Ellie Stager made a bow tie for her husband Andy out of some leftover seersucker fabric in spring of 2009. When Andy posted it on our twitter people started asking if they could get one too. Pretty soon, we set up a sewing studio in our spare bedroom and started sewing away. And before we knew it, what started out as a hobby turned into a business."
These companies produce superior quality, handmade bow ties on site here in the South.
One note: Southern Proper has an inventory of fun bow ties, but their ties are made in New York.
