Lots of Googling, then a little calling around. I started with one in my neighborhood who also runs a hair salon, who was also the only one I found who specifically advertised a masculine-specific wardrobe assessment service.

When I described my problem, she gave me a shortlist of several other stylists who were outside of what I thought I was looking for, like FernDate, Duchess, and some local vintage-specific pickers who just aren't online.
