Need hair advice!

So I haven't been feeling great about myself since I had my son 5 months ago. I dont get ready or do my makeup anymore. I basically wear sweats and rock the no makeup face unless I'm going to work. (I'm a part Time waitress). So my fiance told me I could use some of our tax return to get my hair done, my eyebrows waxed, and some eyelash extensions If I want them. Basically a little mommy makeover. But cant decide which hair color and cut I should get. My natural hair is blonde. Suggestions?

These are the three I was thinking. I really like the cut and color of the first one, but again, not sure if I could pull it off. What do you ladies think?

Here is a picture of me now just for reference.
