I like the 1st one and the 3rd one, as I get my hair cut like this and alternate between the lengths. The first one is good if you want it a but shorter for the Summer. It feels lighter on your head and cooler. My hair is more like number 3 at the moment though. :D
I'm not a fan of those bangs, but every now and then there's someone who really pulls them off (like the blonde at the bottom.) So I mean if you think it would look good on you give it a try. And if you don't like it you can just tuck them back and it won't even look like you have them!
Don't cut bangs. It was one of my biggest mistakes. I'm someone who isn't prone to acne and after cutting bangs, my forehead broke out and it was hard to remove the pimples. Also, your bangs go through an awkward stage. Also, they take long to grow back. My hair reaches just past my breasts and my bangs finish right before my breasts. This is two years after cutting bangs.
