Of course you may use it as reference! I always find looking at other cosplayers work on a costume makes it so much easier to figure it out yourself.
Hmm, tips...I guess the #1 thing for me is, sew your wig to the hat if possible. It made the wig and the hat stay on much better, and I could get better volume with the ponytail in the back. The only thing is that it makes it a little more difficult to put the wig on. Other than that, it's a pretty simple costume! If you have any questions let me know here or on my FB page (I'm probably more likely to answer over there because I check it more often)
