The reality is, most people who attempt to make money from cosplay don’t make very much. If you can sell merchandise, get sponsorship deals, or regularly get hired to man booths at conventions you might be able to make $50k-75k in a year. If you do get to the point of being a professional cosplayer you can make a liveable income. I will still have the fur suit commissioned, because it takes years to get great at making those, but I will probably do enhancements to it myself, such as how I added the grey fur to my ears this year.
