Well, remember, as they say, google is your friend. Here's a start from Kohl's website:Q: Who do I contact if I am interested in modeling for Kohl's ads?A: Normally, we work through Milwaukee-area talent agencies like Arlene Wilson's and Jennifer's Talent to find fresh faces for our print and broadcast advertising. We also work with talent agencies in areas surrounding Milwaukee, like Elite, Ford, Arlene Wilson's and Aria in Chicago, Illinois.
Otherwise, your models 1, 2 & 8 all look to be the same girl. Perhaps this is the model you describe as the "older looking lady". Not sure. In any case, she has also modeled for ideeli.com recently. Here are a few pics:
As far as I can tell, Ideeli seems to be based in New York. I've perused them a bit lately, and they've used quite a few models from Next. I've tried looking for this girl there, but Next's website is a bit slow and hard to use for IDing. Perhaps another set of eyes will find her there.
