My advice would be to set a budget, and them find the best quality you can get at your budget level. If you wear suits everyday, you'll need at least 5 so as to not run them down right away. There definitely won't be many, if any, first year analysts in any business donning Kiton, more like Brooks Brothers, but if $20,000-25,000 isn't an issue for you, then get 5-6 classic (navy and charcoal, 2 or 3 button, side vents and no wacky patterns) Kiton ot Brioni suits and they'll serve you well for many years as you climb the corporate ladder and they'll always be in style. Ideally, you'll need to add suits to your wardrobe so that you wear a suit once every two weeks at worst (10 suits). You can go cheaper and still get quality suits and have money left over for other stuff like food, but it sounds like you're a big hitter.
