The main two potential sources I have are:
Wetwear in Florida. Their calling card is that they have been doing suits for a long time, they use genuine Rubatex G231 (the very best there is for real divers) and they can supply custom made a vintage type suit. They prefer to work with a nylon two side material for durability since they have a warranty.
Terrapin in Texas, I have bought from them before, also successful for many years. Custom only and a bit more pricey. She uses only Yamamoto neoprenes and some Shien blended cheaper stuff. She can do skin out and may be willing to discuss ordering special texture out Yamamota skin out neoprenes. She also has made beaver tail suits. Terrapin will work with individuals only, no group deals I don't think.
Both of these would be sewn suits and then double glued and reinforced. They both will do either raw edges or finished though again for professional reasons they prefer finished edges.
Historical fact, in the late 70s and 80s most domestic quality manufactuers went away supplanted by all of the foreign sourced and slave labor made asian products we see on the LDS suit racks. Cheap blended neoprenes that compress and flatten out--sometimes forever--after a deep dive or two.
OK, please feel free to comment and add your sources or ideas. No, Luis's charturse neon trimmed suit is not --uh---never mind
