I’m making a costume of Hollow Knight guy for a trip, and I have already made a 3D printed mask w/ cut up leggings to cover the eye homes. Additionally, I have some long sleeve pants and a jacket to have a dark body, as well as a 3D printed channelled nail.

But now I need to make some sort of blue robe. A few people online doing something similar has suggested getting some oversized t-shirts and cutting them up, is that a good option? How should I cut it up to make it look like Hollow Knight guy?
