Help me choose a hairstyle!

[Matryoshka]

I had really long hair most of my life, but when DS1 was about 1 year old i got it cut quite short when the concave bob came in to fashion. I just didn't have the time to look after my hair which is fine and wavy. So unless i straighten or style it, it looks messy. I got a bit sick of the bob after about 2 years and missed my long hair so started growing it again. But i've since realised i still don't have the time to style it so i end up just wearing it up. The bob suited me, and googling i've found lots of versions of it, i've uploaded some pictures... just after your opinions of the one you like the best as i can't really decide. I need some major cheering up so am going to print out which ever photo if i can make a decision, and go tomorrow to get it done.

Hope you can help!
