That sounds like a neat shirt! I have a batman sweatshirt, but it's just black with a yellow logo. Cute and simple.
I'm presently wearing pajama bottoms and one of my boyfriend's old thermals that he didn't want anymore.
I usually don't like sleeping in long sleeve shirts because the sleeves get so restricting, but since this is really big on me (he didn't want it because it was too big for
him), I just woke up super cozy.
