I wore Depends two days last week. That burst a few myths for me.
1) They are NOT comfortable. They always feel sweaty. They rub on the legs. If/when I really need disposable undies full time I will try every brand in different sizes to find the least uncomfortable for me.
2) They are NOT undetectable under clothing. They are bulky. The "panty line" shows. I wore tunic tops. Long loose tops are the best camouflage, I think. A loose skirt would probably be most inconspicuous and convenient.
3) With slacks, they are NOT easy to change. Can you imagine taking off your shoes and slacks and disposable and going through the entire process in reverse, in an airplane lavatory or most public restroom stalls? A skirt would make it someone easier.
They are necessary and awesome in some circumstances, and wearing them is better than bringing your life to a halt because of incontinence. Thank inventive minds that they are available! But as wonderful and necessary as they are, they do have drawbacks. I hope it is a good long while before I have to use them ... if ever!
