Okay, I think I'll check out Tino's and Cornell's for suiting and Sapatero for shoes. Do you know if they are receptive to visits to check out their wares?
I also found Signet (I think previously Lost+Found) and it looks like a shop worth checking out?
Are all these 4 shops close by where I can see them within a half day? I know traffic can be notorious so I want to be efficient.
