Congrats on the new job. I buy most of my pants and suits at Ann Taylor. I don't have an incredible amount from which to choose in Indianapolis, but for the money, they are decently cut/made. I've had good success lately with J. Crew for separates, e.g., skirts, blouses and the like. I find a few thing at BR too, but it's more hit and miss.

I hate spending money on clothes (that arent' cycling related, that is), but I'm really particular when it comes to suits. I'd rather have two good suits then five not so good ones. I prefer wool and won't buy anything that isn't lined. Also, I would recommend staying away from pants--suit or otherwise-- with a low rise. I realize that stores that cater to professionals, like Ann Taylor, are selling them, but I don't think they're overly professional. I tend to mix and match my suits/separates too. I just bought some wool pencil skirts at J. Crew that I can wear with most of my suit jackets.

Happy shopping!
