Here is irl pic of the black ones I got so you can get an idea of what they look like on:
For me they ran 1/2 small, I usually am a 7 but got a 7.5 (this is the second pair of Kenzie's I have had to do that in). Hope that helps you. I also think #1 is cute.
i like #2 because i think it looks nicer for the office, but would be equally nice for going out. #3 is nicer for casual if that's more of your focus.

I voted for #1 because I think they would work best for both work and going out. I think they'd look great w/work pants, jeans, and skirts. I really like #3, especially after seeing them on FP , but I don't know how I feel about that wedge w/your work clothes.
