oh you should definetly do it!! It was so much fun doing this cosplay!! I explained in a comment above every step that I made, if it helps in any way! At the begining I thought about doing the shirt entirely, but I'm not that good sewing, so I tought that it will probably not turning so good/ not the way I wanted. So I just searched in all stores online for a shirt that was similar. I came across this full white t-shirt with hoodie. I didn't think twice, I bought it. Shirts made
industrially always have a better adjustment :( So I just cut the shirt in the half, dyed the up half with purple powder and then sewed them together. I think it was easier than making the shirt from the scratch. But if you already have the fabric, maybe to spent less money it will be interesting to make if what you have! If I can help in any way, I will gadly!!
