Well, we saw these neat hats on Lolita Kisama, and we liked them.
But we decided to make our own. So, for D I made my version of Bunny Bou, which we call Bunny Bee
And mine was an original design inspired by about three different hat designs. Mine is called the Rad Cat Hat, because it's fun to say.
This hat is excedingly comfortable, and very very affordable.
