[@autumoon] And if you're looking for someone already dressed for a period piece, just look for obscure movies. Everyone likes to make lists of their favorite B-grade movies, and they can be used as a catalog for face claims. Pick a genre, google "(your genre here) movies" and you're bound to get a few lists. Then you just need to pick a movie and boom, face claim with appropriate attire and a name. 

You might also be interested in looking for models, but they tend to not give their names whenever they can. They are a [i]very[/i] good source of unique appearances and can be found by looking at fashion websites. Celebrity fashion is also a thing, and they are almost always named. But you might find that they tend to follow most of the big name actors.
