When I was in my nice clothes phase, Bachrach was my go-to store. (Two out of my three local ones have closed recently, due to the economy.) Some of their stuff was a bit too too for me, but other stuff really worked well. The staff was really good at putting together outfits. Apparently I look best in "jewel tones."
I don't shop there much any more because I don't want to have to think about how to get toddler vomit or boogs out of a fine silk shirt.
Among department store brands I really like Perry Ellis. It's more of a "after work I'm going to a club" look. I prefer that to the "I'm a sailor on a yacht," "I play golf!!!" or "I'm a street thug" looks that seem to fill the men's departments these days. But again, these days for me it's more chinos and polos (summer) or merino sweaters (winter, see other recommendation upthread).
Jeans I just order from Lands' End. They're OK. Nothing great. I don't have the mental energy to find anything else.
I can't seem to wear cargo anything. The pockets seem to get caught on everything. Seriously, if I'm wearing cargo shorts and walk by a knob or handle, they're going to get caught on each other.
macy's here especially with those discount coupons around the holidays.
