I had to wear a suit every day at one of the Wall Street firms that I worked for. The reality is that a "good" suit is going to be expensive - there is no way around that. If you don't want to shell out for a bespoke suit, you can also find very nice made-to-measure selections at upscale stores like Neiman Marcus. Prices vary wildly, but you are going to be looking at a minimum of around $2-3K for a decent suit. Also, if you're going to wear a suit for work and not just once a year to a wedding or whatever, you need to remember that you'll want two pairs of the slacks - you don't want to buy a $3K suit then tear the slacks six months later and find out you can't get that particular fabric anymore.
