Try Talbots as well. They have decent quality, great sales and virtually everything comes in sizes from 0P to 24W, including Women's Petite. I'm just over Petite height (5' 5"), don't wear it in anything else but the Petite has saved me loads on alterations in jackets and coats. They have tons every season. A couple blazers in a tweed or other mixed color palate can go far to make lots of professional looking outfits. All their suits are purchased in pieces, so if you need a bigger jacket and smaller skirt/trouser, you're in luck.
