Boz,I am not sure if this is official policy, but my former boss (partner in charge of my practice group) was an ex-McK-guy and he told me on the first day- only white shirts- only black shoes- only grey suits- no printed silk (which is for sure the case in France)- no socksbut if you have already been in the office you should be able to match their dress code. The issue might be a bit Brett Easton-Ellis, but aren't we all bit Brett Easton-Ellis
