I'm looking for a hairstyle with a color similar to the one I have now, that's most important. I also would like for it to have swoop bangs, and be medium length. Any suggestions?

Well you could always just use a default and change the colors to what you want, which is what you're currently doing, no? I can't think of any wigs that are truly similar, but I'll continue looking throughout the day. The default styles I'd suggest are: coffee, flick goldilocks, scene, waved, wick.
