Im about a 30-31 waist and i find uniqlo slim fit jeans(31 waist) fit pretty well over a nappy without showing off what is underneath. They are fairly low rise though but if I'm wearing around people who don't know, i wear something like an attends slip active which has a much lower waistband...

2 cases + 13 Plastic Backed tena slip maxi
9 tena pants super
