Here's a couple different pics of me - I have a round face, and right now my hair is past my shoulders with a lot of layers, and I have side-swept bangs:
(I'm on the right)
Here are the cuts I'm considering:
1.
2.
3. (Could I pull off bangs like that? I'd probably get them a little shorter...)
I have a similar hair and face shape to yours and got bangs the last time I got a haircut. They didn't last very long (my hair grows fast), but when I had them I really enjoyed them.
ETA: I got my hair cut short recently and I kind of regret it...it was fun while it was short, but I get a lot more compliments on it when it's long and I am not loving the in-between state my hair is currently in.
Why not try them all in 3-2-1 order? If you're not too attached to #3, go even shorter and get #2 after a couple of months. That would be super cute for Spring. I'm not sure there's a huge difference between the #2 and #1 cut; it looks more like the variation is in the styling (#2 is curled and teased/bodified a little while #1 is straight and piece-y). I think any of these will look good on you, but I would probably go with #3 since we're only supposed to pick one!
