There are some fun hooded bath towels out there. Check out Tubby Towels: same themed hooded towels for adults and toddlers, appropriately sized. http://tubbytowels.com/towels.html
I wanna get a bunny towel.
I much prefer robes or wraps, of which I have way to many of, lol.
My super fuzzy Joe Boxer fushia (bright pink) hooded fleece robe, great for winter!
I have totally slept in nothing but this, well and a diaper now , more times then I can count, it is just that comfy and cozy!
Oh, I have one of these: Super Cute! Hello Kitty bath wrap it closes with velcro across the top of your chest, did I mention So Cute! Yes I am a child. But it's in the juniors section. lol
And when I actually want to at least "look" like an adult, lol.
I have my VS Love Pink terry robe, red with cute pink polka dot trim, great for winter too!
And of course I have two shorty satiny robes, "grown up" red and "not so grown up" pink with red hearts, lol.
The more and more I examine my wardrobe, the more I realize I have been a "grown up" teenager for far longer then I think I care to admit too, lol.

Yaaaaaaa ............. I probably went a bit off on my own there, didn't I?
