This is just heresay b/c I have never shopped there before...but several of my friends say that they have found good, classic suits at Casual Corner.
That being said, Ann Taylor's fall sale should be coming up in a few weeks when you will find lots of suits 40% off. I am a huge advocate of AT b/c while you might pay a bit more...they are extremely well cut, well made, and classic.
I am currently trying to build my suit wardrobe as well so if I come across some stores with good deals I'll let you know
