Yes I have two black ones from North shore and I need to get more. I have found them to be very useful to help hold up the diaper when it is getting heavier from being wet, or to help hold it up when I am walking on the treadmill.
I used to when my wife was alive. She was the one who gave them to me, auctioning on Ebay. I was lucky because I could wear a diaper under my Donald Duck onsie and sleep right next to her as a little boy.
Yes, one blue and one white. I'm a mechanic so constantly bending over at work, and I can do so without exposing my nappy. I like wearing them in bed on cold nights too. The buttoning up process generally adds to the safe and secure feeling of wearing nappies.
Have a few different types already, considering only started wearing last month, but my favourites have to be tykables romper, its like a pair of boxers and a teeshirt, and in the crotch, loads of poppers, think its 6 poppers, must check, at the mo have a different type on that is more like a vest/leotard, quite nice as well, only 3 poppers in the crotch.
