Which one is the prettiest...?

Not 6

Those are all quite ugly

I would've gone with different colors, but 3 and 5 were the least annoying to me....

4 & 7 are cute

Just cute

No comment on the rest

..... what is the dot on the bottom of her boob in 6?

all white?

4 I guess but with a different belt

Anything Blake Lively wear

#4 and #6!

#2 is my vote

I don't know who it is. I only recognize one Emma Stone, and she's near the bottom.
