Most Helpful Guy
I think all 3 are too much for me. Those hairstyles fit some gala event, cocktail party, something really fancy. It's not that I don't like them, but it's just too much. If I have to choose, I'd go for #1 because then I can still play with her hair without worrying too much about messing up her hard work she would put into #2 or #3. With #2 I'm afraid I'll just ruin her hair when stroking it and putting it aside to kiss her neck. With #3 there's no hair around the neck to push away.
#1 is simple, elegant and there's something to push away to reach for the neck - without worrying to mess it up.
