Wrapping up my last cosplay of 2017 with something simple, Yukako Yamagishi from Jojo's Bizarre Adventure: Diamond is Unbreakable.
There should be a lot of seifuku tutorials out there in the internet and I feel like there's a general conventional method in making it but I had a hard time following some of the tutorials I found online. I did find one really helpful seifuku tutorial that served as my starting point. However, it wasn't entirely complete so I used a basic bodice and sleeve tutorial as the main guide. You should really watch those videos first if you want to go through with this tutorial.
