I can see the lower end of ABDL sizing being a problem, if you can still fit in Pampers. Rearz' smallest sizes start at 24" waist size, which is the size chart standard for an 8-year-old, and Pampers sizes 7 & 8 will fit on a typical 8-year-old, so in theory, a Rearz size small diaper in any of the prints, should fit on you, although the range on the small sizes goes up to 33", which means at 24", the tapes are going to basically be on top of each other, in the middle of the front of the diaper.
Maybe check out Youth Crew diapers? They're "baby-style" disposables for bigger kids, and their size 11 covers 23"-26" waists, so unlike a Pampers disposable designed for someone who weighs 46 lbs, being structurally abused in order to fit an adult, the Youth Crew products are not going to be at V-max on someone in that size range. They have a sort of checkerboard pastel print on them.
I'm avoiding using AI for photo-realistic images and art out of respect for the content creators and artists out there, but for quick everyday graphics I wouldn't hire an artist for anyway, it's wonderful!
Where else can I get a "Cranky When Wet" warning sign in under twenty seconds instead of spending an hour creating one myself that would be no where near as good. Oran image to go with this post. [Promt: Make a sign: ThingsI like: Diapers, cookies, A.i.]
