I regret not doing this when I was in college. The closest I've come to it is while it was completely concealed. Drove out after a snowstorm once with my diaper and footed PJs on, but had heavy boots, sweatpants, and a winter coat on to hide it all. Very nearly got stuck in deep snow, and started thinking my life might get more complicated over the next couple hours. Now, at this point in my life, I don't know if the opportunity to openly wear my pjs will come up. But I will always be on the lookout for it.
