OH, and as for kiliarara, my vote is always for styling your own wig IF YOU ARE CONFIDANT THAT YOU CAN. My biggest pet peeve is badwig, so if this is your first time trying it, don't start with something like that.
Buy the wig. Get it right, not homemade. If you want the costume to look good, the wig has to look good, and if you don't have the skill to make it yet, which, if this is your first, you really, really don't, then don't do it.
And yeah, that one looks good.
