((My first time cosplaying Sasha I used a wig. I was a part of Crunchyroll’s official cosplay group for promoting Attack on Titan at Anime Expo this year, and all of our wigs were provided to the group by our sponsor, Epic Cosplay! :] I used their 20” Spikable Layered wig in Dark Brown as the base, and then their 30” Straight Ponytail Clip in Dark Brown. I would suggest going a few shades lighter since it looks pretty dark in many lightings.
All I did for styling was trim the bangs, pull the base back into a small ponytail, and trim the extension which then clipped onto the small stub of the base wig.
Now, though, I use my own hair since I cut off about 8” and have been keeping my bangs more the correct length. So all of my nice photos are from when I had the wig, but all my answers and current photos are with my own hair. xD It’s kind of weird.))
