Glad you're out of the water then
Would be funny as hell if the Fireflies actually looted some ABDL store "Because we had no idea what we were looking at, only when we finally got inside... then realised why this place wasn't touched" and come back with intentionally bulky and ridiculously girly nappies :P
Another possible point for cloth then, tends to be bulkier than disposables and because of the fabric it can have a lot higher variety in cutesy prints

Well, it remains to be seen. Maybe some puffy-frilly rubber or poli-fiber diaper covers.
