How many times have you been tricked by titles like "Awesome Halloween Costume Ideas for Lazy People", only to find them all requiring more than a minute to assemble? Do these people even know what "lazy" means? Luckily I came across these costumes which are truly one-and-done. IMO you can ditch all the accessories and people will still recognize your character. Dedication with minimal efforts, y'all.
If you have a better idea than these, you can even upload your design using the website's built-in tool. Then you can either order it for your own use or publish it for sale.
