I like the girly look myself! That outfit looks great!! The preppy one is ok, but I like more of a beach look on girls. Hair a little messy like it's salt kissed, and stuff you'd wear in warm weather in a beach town. I think that is the sexiest look. But the girly one pictured is nice too. None of them look bad, but I'm not a huge fan of the grunge look.
Gosh that us hard I love number 2 but number 3 man I think I would just be more attractive to me that signals more layer back but I'm also trying it impress you. But at the same time number 2 would make my jaw drop and I can't say I would not be thinking sexual thoughts at number 2 either.
