Yep - huge difference between east coast and west coast. If you wear your Ferragamo shoes, tie and tailored shirt w/ initials to a west coast office, you'd most likely be over-dressed. But in NY that's just the standard outfit.
Thomas Pink, Brooks Brothers...all good brands. BB's non-iron shirts are pretty low maintenance. Although I find their styles a bit too conservative. Then again, I am based out of west coast now so there's no need to dress as formally as NY.
