Theory - shoulders were cut very slim for me, had to go up 2 sizes bigger than I normally wear
J Crew - quality not as good as Theory, wool pants are itchy, but good conservative suits that won't go out of style
Benetton - again not a big fan of the material, but the cuts are good
Elie Tahari - more mature styling, uses more synthetic materials
Club Monaco - for pants that are more fashionable in wide legs or skinny and a lot of the jackets are cropped, I think the the quality of the wool is pretty good, not as good as Theory, but better than J Crew
BCBG - haven't been in for awhile, but remember they had so fashion cuts, and the quality was ok
I haven't tried it in person, but the Alvin Valley wall street suit looks nice.
I do not like Ann Taylor and Ann Taylor loft because the pants fit weird and the high v in the jacket.
