Yeah, small shops tend not to carry much inventory, especially the higher end stuff . . . it basically comes with the territory when you get into the world of custom made clothing. Shops like Spoon Tailors are basically a cottage industry. You just have to patient. The suiting selected had to be ordered too, which took two - three weeks.
I had my first fitting last week and I was impressed. I spoke at length with Andrew and the cutter (Andrew and Kevin's father I think). One thing that ought to be noted here is that Spoon simply a MTM tailor. Their process definitely passes the criteria to be considered fully bespoke.
1) Andrew or Kevin take measurements at the consultation
2) A very generic pattern is cut
3) At the first fitting, the cutter notes how the basted pattern sits and what need to be done
4) Per what he sees at the 1st fitting, the cutter re-cuts a unique for the client
5) Subsequent fittings occur once the garment is more finished where details are dialed in
