Your first model casting -- what were you looking for? How worried were you when you were told that you couldn't replace one of the models?
I was looking for ... a bit of a curvy, feminine figure, long hair that could be styled into fat full curls, and diversity. I didn't want that typical clone-looking line-up. Then when I was working on fitting and seeing all the girls in the clothes, I worried if I went too diverse. I didn't want to look too inconsistent. I was worried about not being able to switch out girls. In the end, with hair and makeup, the line-up was exactly what I visualized and I was happy. I overreacted.
