Sorry to bump such an old thread, but I recently discovered Samuel Parker in Baltimore, and I was very very impressed with the shop, and Ken as well.
The term SF Apprved get thrown around a lot, but I would say that Samuel Parker has the overall asthetic that many on this forum are looking for, suits and sport coats from Samulsohn, Polo (blue lable) and Southwick, shoes from C&J (via Polo) Alden, and he had a trial pair of Alfred Seargeant boots in the shop :-) shirts from Polo and Hilditch and Key, socks from Panterella, and ties and PS from Drakes.
Prices are not cheap, but not outrageous either, right now he is running a %30 off fall winter merch.
In talking to Ken he has a very SF type of sensibility, he doesn't carry black suits, he prefers two button or three roll two, and side vents with a soft shoulder, loves tweed and texture.
It's worth a trip if you're in the Baltimore area.
I picked up a pair of Alden suede chukkas, some Panterella socks, and a silk/wool PS from Drakes
I will be back to is shop.
