Journey's (which is actually a fabulous shoe store) is selling this hideous "outfit". Their stance is, "Who says kids have all the fun? Channel your inner child with this fleece onesie."
Umm...no thanks. I admit, I do tend to wear pajamas sometimes when I'm at home, for comfort purposes. But even my pajamas are not horribly embarrassing. They're actually quite cute. This onesie just is not acceptable, even for wearing at home.
And yes, I'm sure that it's very comfortable, but that doesn't make it okay to wear.
Oh and if you happen to be one of the millions of people who think that wearing pajamas in public is cool, here's a tip: This onesie is not socially acceptable in the real world. You will get your ass kicked if you wear this in public. That's a promise.
