If you like a funny costume t-shirt then this is the one.
It looks like it is just a plain colored t-shirt with a sign on it stuck with tape and on the sign, it says “I’m cosplaying as myself”. Of course, the paper is printed on the t-shirt making it perfect for wearing over and over.
Now you can dress up any day you want as you have the perfect costume t-shirt just waiting for you in the closet.
And besides, for cosplay, you could wear it on Halloween too.
