+1 for the correct use of "pique," though I assume you mean that you want this to satisfy your curiosity rather than raise it.
I voted "other" because I dress normally when I'm wearing a diaper. Maybe it's because I'm a DL and have no AB tendencies, but I've never had any desire to wear anything special with or over my diapers. I like putting on a diaper and going about my business as I do my business. That's the fun for me.
I ticked "Tshirt" because that is my normal attire around my place but I do like to wear a pad in my pullups, and sometimes even a pair of undies. Unfortunately I do not have my plastic pants to wear at the moment due to an "destructive argument" with the dryer....lol
I like to wear something that's comfortable, usually sweatpants and a T-shirt while at home, or if it's hot out, a pair of shorts instead of pants. I also usually have some underwear on over the diaper to help keep things in place.
I always wear a t-shirt (all my t-shirts are onesie-type); If I am wearing a cloth diaper, it is always plastic pants over top of it, if I am wearing a disposable I don't need plastic pants; then my regular clothes-jeans or shorts during the day, flannel pajamas at night.
