Jeeze, I'd find a tutorial for stubbing a wig and stub the two pigtails, then get a hair fall for the back?
Or a really long wig and tie it into a lower pony tail and then stub the two pigtails?
I think you really need to stub the two front pigtail things. Which means you have to find a wig that sells, hair falls, extensions, and actual wigs XD
You could start with a lulu
get this for the back clip
And rip apart a long wig for the extensions.
I dunno if it could be done but perhaps you could use this straiten it and pull it up into really high pigtails?
I'm really not very good at this stuff xP They don't really have that purple >.<
Airily has the PERFECT purple
but you'd have a wig that would cost more then $100 if you got everything from them (base wig $60+ two hair falls $80)
