Of course it isn't, it is actually my costume, and as she is ten and I am older and have a bigger body and breast size, the costume doesn't fit. I couldn't find the correct ribbon, and I have been too lazy to even begin on the wings yet. However, it was something we just slid into and took some pictures. It was her first time cosplaying and we had loads of fun.
I can see what you're getting at~ I see the hooks as well in each picture now, but, its not actually oversized, its undersized! XD Her head is much bigger than mine. I tried everything to adjust the hooks but in the end I had to just unhook them. They are sticking out of the edges (something I should have caught, only it was freezing outside and I was worried about the both of us getting sick from that.), however, I assure you that the wig wasn't too big. If anything, the wig was too small. The sideburns didn't match up with her sideburns, maybe her ears are a little far towards her face? And the wigcap I had her wearing didn't help very much either. In the end, I might blame it on the wig quality. While the fibers are really nice, heat resistant, and soft- the quality of how it was put together isn't exactly the best. Also, she's so dead set on just cosplaying Cirno and PC98 Alice, she's asked me to make her a Cirno costume. I don't think she'll cosplay as Marisa unless I surprise her with the costume. It could be a good plan though. =3 Thanks for the suggestion.
