i voted for number 2 because its something i have never seen you really wear before and it looks great!! number 3 also came in a distant second. anyway love #2!!!
i like different parts of every outfit, esp. #2 and #3. by any chance do you have black shoes that don't strap at the ankle? they kind of break up the line of your beautiful legs, some slingbacks or mules would be way flattering imo. oh and i love the shoes in #4.
I actually ended up with tons of compliments on that "simple" outfit and it looks great on you too. I agree that a sandal without the ankle straps would lengthen your legs. And if your anything like me - I need that!!
#3's skirt is fantastic. And I really like the ankle strap shoes. I think they make your legs look super-sexy in those pictures. You WERE going for sexy, right?
