I have no idea where such a shop exists, especially since I'm not welcomed in places frequented by the "well heeled." I got too much "stuff" on my boots.
That pretty much sums it up for me too. (I wouldn't want to join any club that would have me a member).

I think if I walked into a shop that caters to the "well healed" they would call security and escourt me to the door post haste.
