Absolutely. Forgive the psychobabble, but the black community has always appreciated a finely dressed person. And religious people of all kinds associate it with clergy. Either that or they figure you for law enforcement and that gets their attention, as well.
I can't even count the number or times I found out that someone initially thought I was the PoPo. When they found out I wasn't, you could almost see a light come on and they would start to open up.
