I would start out with a white blouse personally, to compliment the white lace. Black could work, but it would be harder to coordinate. Since the jumperskirt and blouse are simple, solid colors, you can get a little more creative with the socks. Something like these
would be creative but still coordinated, and add some interest to the overall look.
Side-swept bangs are perfectly acceptable these days, and I prefer them myself as well. What is your skin tone? Black wigs look kind of stark on some people (I could never pull one off myself without looking too "goffick") and depending on how dark/light or pink/yellow your tone is, I might recommend a chocolate brown or milk tea color instead.
Do you want a head-eating bow, or something more understated? A big black and white bow like this one
would lend to a very classic "old-school" look, or you could tone it down with something smaller like these smaller ones
or a lower-profile side bow
I hope this helps, and good luck! Feel free to PM me for more ideas, I have lots of examples.
