As you all know, The Fashion Police try to avoid getting involved in matters relating to what people wear in the privacy of their own homes. It's out of our jurisdiction.
This advert, however, appears to suggest that it's entirely appropriate to wear an adult onesie to "the ball game" and in other public places.
This is why civilisation is doomed.
Watch and learn, people. (Also, look out for the big selling point: you don't have to remove it to use the bathroom! Er, yeah.)
