No I've not. It's Thursday lunchtime here, and I can't YouTube from work! I will go and look at it later on.
(I can actually tell you how bloomers work, in terms of the mechanics of being able to use the toilet while encumbered by layers of skirts, petticoats and voluminous underwear. Many early bloomers were 'splitters', i.e. crotchless, or had a removable panel, so didn't have to be completely removed in order to urinate. It wasn't until the late 1910s, when women's fashions became more practical and simple and allowed more freedom of movement, that full gussetted underwear became the norm. WHY DO I KNOW THESE THINGS?!)
