The cost of a fursuit will vary depending on whether you make it yourself or purchase it, and how fancy it is. Some people have made their own fursuits for a few hundred dollars (the head is often the highest cost due to its intricacy). Professionally made fursuits tend to cost in the thousands. You might be able to get a used fursuit for a lot less by checking trading and auction sites but check it’s clean and in good condition before buying.
