Wow. The wig looks nice. I almost want to snatch that deal from you. You can take a look at my wig here http://www.tia-moon.com/myCosplayPhotos.html
. I thought it looked pretty nice. its not that long though. You should ask the seller how long the wig really is. and then take a tape measure to your head to get an idea of far down it will fall. When I bought my wig it looked really long on the foam head but when I put it on, well I still think its long since I am not used to long hair but I guess not long enough for being an anime character. lol... also. Cut some more bangs into it. My wig did not have any bangs and the lady at the wig shop cut them in for me. She did a good job. she also teased the bangs. that made them even poofier..
And the thing about the platinum blond. U can barly tell but the wig I used was platinum blond. Only if a few pics when the light hit it just right. Good luck on your costume.
