In the DBZ forum there is a thread on the socks:
A few ideas in there.
The wig you will not find. You will have to create that poof yourself or have a commissioner do it, but really it's not a big deal since that will more than likely not only be more trouble than it's worth to style, but a commission will cost a ton..
This wig would do fine in black:
You will have to cut it, but if you are dead set on styling, it should also be long enough (in fact it will still more than likely need to be shorter even with styling)
The rest, go buy jeans, a black t shirt, a white long sleeve shirt (if you can get a black tee with attached white sleeves get that..Less layers lol), some blue converse and an orange blank bandanna. Then you can either find or commission the Red Ribbon Army logo or try to make one yourself if you can. Rip a little tear in the left knee area and bam done.
By the way, I commend you for doing this. I LOVE the Android siblings, and plan on doing 17 once I find an 18 to go with me.
