Hideout, used to be in Royston, Herts but i think they've moved to Essex, or MW Leathers in East London, or MJK who are somewhere in Hertfordshire as well. They've all got a good reputation.
Hideout aren't that close to you, Roy, they're about 3 miles from the next junction on the M11 after Stansted going north.... but they are very good.
Michael's got to go up there for a fitting shortly if you fancy a trip (I'm assuming they are for Sandra) - or they'll be at Ally Pally so could go there to have the initial measurements taken.
I had a chat with BKS at the NEC and their stuff looked good. How do their made to measure suits compare with the others mentioned in this thread? I was planning to get measured at Ali Pali. I'm guessing BKS are the most expensive but is it worth the extra cost? I don't mind spending the money, but I hate wasting it.
