Dave,
A question for you, and possibly for other people to chime in on as well.
In your time doing this have you noticed that some clothes do not show a visible wet spot on them? I am referring to the most recent set with Jasmine where this happened according to your description comments. I have remembered a few other times in the past where something similar happened as well. That the clothes seem almost water proof that a lady could pee her pants and nothing would visibly show on them. Do you have any reasoning behind that? Maybe manufacturers know that something might happen so they design some that will not show anything.
