I have been to Chuck E Cheese wearing a diaper.
I've worn a cute shirt and a pair of shorts and sagged them some to allow the diaper to be shown.
I wore an Abu Little Pawz diaper and loved having it exposed and I wet it as well and the bulge showed through my shorts.
I remember seeing a boy of around 6 years old in Chuck E Cheese last summer wearing just a Pampers Cruisers diaper which I assume was a size 7.
He was wearing just the Pampers Cruisers diaper and a shirt and his shoes.
He looked very happy to be in his diaper and was eating and then playing games and I wished I could be dressed just like him.
