http://www.all-about-style.com/victorian.html I remember a lot of peasant/working clothes there- victorian section (or was it the themes section- can't really remember, but there's some great stuff over there) 

 Edit: Duh, there's a medeival section under themes, but I remember some in career outfits as well. You might want to look around 

 My memory is not so good these days...
