You'll find a wealth of experience here I'm sure (sadly not me!), but you need to give more background, e.g.:
- purpose of suit (wedding, work, etc.)
- personal style (classic / formal / bit more up to date / flashy, etc.)
- what makes you think you want a Savile Row suit
- have you had Made to Measure or Bespoke before
And things like age and build might be useful.
