I have this long orange wig I use to cosplay characters such as Orihime from Bleach and Shirley from Code Geass. Currently I'm working on a new cosplay(Saki from Eden of the East) that requires said wig to be styled into a bun. I'm having some trouble doing so though, as the sudden weight of the rather sloppy bun makes it difficult to keep the wig on.
Any suggestions for how I could still put my wig into a bun without the whole wig itself slipping off my head?
Note: I can't afford to buy a new short wig and just clip on a bun. In addition I was planning to cosplay Saki next weekend. @-@;
