Ok lets put this one to bed with some sense. Buy 1 suit, the best you can afford, preferably a 150 grade wool, in charcoal or navy, perhaps a pinstripe if you like (in which case the wider the better upto 1 inch). I'll say it again - buy the best you can afford. Then look after it. You can vary ties, shirts, cufflinks if you want, although for interviews I would always advocate a clean white shirt, even buying a cheapish new one for each interview to ensure it is immaculate. Finally, black shoes either brogue or oxfords, leather soles (no rubber soles please). Dar tie - should always be darker than your short incidentally, and preferably plain, any colour you like. Pink ties look great with a navy suit. Last thing - the suit won't get you the job anymore than your CV will. The CV got you the interview, the suit will get you past the first 30 second evaluation of whether you 'fit' as a consultant. i.e. look smart, make the effort etc, "one of us" cultural nonsense. Now concentrate on the interview for the job you want and stop worrying about your suit - leave that to used car salesmen.Done.
