Everything about this is wonderful. <3 The shading, the sheer accuracy, your props and materials.... You definitely have a face for cosplay, my dear (which means you're meant to be seen!). :3 Keep cosplaying, you're good at it!
Hello! a friend's mum did it for me (the jacket and the trousers), I did all the cosplay props (i am better at that than sewing xD). I do not really know a seller to recommend you. Sorry. I know it is hard to find good quality costumes on sale, one I bought one and it was terrible, I didn't use it at all.
