intense: "however from what I have read a bespoke suit needs to be put together by a client who knows what he wants and understands all the intricacies of making a bespoke suit"
I think that may have been somewhat overstated. It probably varies from tailor to tailor, but there are certainly some who you can basically throw yourself on the mercy of. Go in, tell them you want some staple suits but you're not an expert and don't know every detail of what you want, and there are certainly some tailors who will help you through the process, making sensible choices for you in some elements and explaining the choices you have to make in others. It's really not the strange and exotic world it can appear; ultimately tailors are running a business like anyone else, and that means they want their customers to be happy and they won't stay in business long if they ridicule someone who wants to buy something from them but doesn't have The Requisite Knowledge. Unless, y'know, they're sniffy Savile Row guys who can trade off the royal warrant they were granted in 1623 for the rest of eternity, or nutty Italians who don't subscribe to the basics of doing business :P
What might give you a bad result is if you go into a tailor with little knowledge but some very determined ideas which are really bad ideas because of your lack of knowledge. Then the tailor is stuck between going with your bad ideas and producing something ridiculous, or trying to argue you out of your bad ideas. I don't think it's a crime to go in with little knowledge, but an open mind and an attitude that you're willing to accept your tailor's advice and guidance, since he knows what he's doing and you don't.
