What about a shorter version of what you have--like a sort of general jawline-length bob? They could give you a few layers to give it some volume and blunt cut the ends. It'd be easy to take care of and still very girlish. That strikes me as a cut that'd be very becoming on you. You have such a feminine face that I don't think you'd ever have to worry about any sort of shorter hairstyle looking dykey. Bobs are good because you can just blow-dry and go or pull your hair back with a hairband when you don't have a lot of time, but there's still plenty of hair to curl and poof out (or use accessories in) when you want to go glam.

I always study hairstyle magazines before I go in for my appointments if I'm intending to change styles. Then I show my stylist what I have in mind and she sort of adapts it to fit me. You have such a pretty face that I'm sure whatever you do will look great!
