Who makes great women's suits?

I didn't realize what a good suit looked like until I was properly fitted at banana republic and I bought one of there suits. The difference for me was night and day from the ann taylor, express or Talbots routes I have gone before.
 
I love Theory for suits, but I've never seen a Theory vest. Theory's fabrics are gorgeous to the touch and the cut of the suits is more modern and flattering than other brands I've tried on like Hugo Boss.
