The hoodie, necklaces and belts were made by me. I also made the cover for the paint can, ahaha.
Initially I wanted to choose greyish fabric for the hoodie, but in the final mission she's shown standing in full light (instead of the dim lighting throughout most of the cutscenes) and her hoodie is more of a pale bluish shade to me, I chose fabric that looked closer to hers in that scene.
I painted the front/back of the hoodie and the sleeves with fabric paint when I cut them out before sewing the whole thing (it's easier that way).
Painted them with a paint roller and fabric paint, like the rest of the hoodie (the paint roller helps to make a slight gradation towards the end of the painted zone). The hoodie wasn't assembled yet, so it was easy to paint each individual detail how I wanted.
Afterwards the paint dries and you can sew all the details together.
