Imagine if this passes and the next day the entire school staff dresses up as furries in protest. "Okay Timmy you see that person with the fox outfit on? That's your teacher today."
Yeah, a decent one is going to be $300-500. For a partial, the head is the most expensive part, and cheaping out on it is a great way to get some S-tier nightmare fuel. Full suits are minimum $1000, but I'd say a good one is at least double that, and they can go into the $5k+ range.
I have a friend who makes mascot costumes. She and her husband sometimes wear them out for entertainment. Little kids absolutely ADORE seeing human-sized Pokemon walking around the mall, bowling alley, or the like.
