FINALLY finished this with help from my best friend
It's not too impressive, and the sleeves are a couple of inches too short, but that's ok xD It's the first ever piece of clothing I sewed myself.
I am considering decorating the edges with silver too - it's for a carneval-like costume. Gray suit pants, this shirt, cape that's red on the outside and black on the inside with a golden rim, silver-and-gold mask and probably black shoes.
