Wedding hairstyle help!

Hey ladies so I have a problem i can't decide what to do with my hair!! This wedding (really a vow renewal) is three years in the making and I still can't figure it out. I absolutely want to wear a tiara, all my aunts did so it has sentimental value, and my hubby loves my long hair so I want to somehow put that into play but the back of my dress is too pretty to have my hair be covering it. So it might just have to be up. I've included the pictures of my dress and the hair styles that I've chosen that I think might work well. Can you guys vote and tell me which one you like best? I'd love to hear your opinion because I want everything to be perfect for this vow renewal wedding because means a lot to me. So please...help?!! Lol thank you in advance!!!
