As for Emma.. never been her customer (for bespoke), so take this for what it is worth.
I once visited the shop for some accessories; Emma was busy with a customer for bespoke shirts, I waited for her attention, so was able to see the whole process. Let me just say that I'm very unimpressed. The whole thing had much more "commercial" and sterile feeling than with both Lachter and O'Flynn. Maybe this is even good for end result? -- what do I know!
