Plus sized women - where do you shop for work clothes

Other than Lane Bryant? I really don't like their stuff. They don't have work clothes (or at least what I can wear - we are not 'business casual' so I cannot wear khakis or twills)

Tweeds are very 'in' this year and so is argyle. I like both! But LB doesn't have either. Where else can I go?

I don't really like H&M - a few outfits ripped the first time I wore each - I do'nt think their clothing is made very well.

Thanks in advance
Mary
