You'd need an old fashioned tin bath - they're actually quite light to carry, and they still make them (or maybe Britain is just backward, but I saw one hanging outside a hardware shop in posh Dulwich, South London last year). I'll try and scan you in some stuff on costume later today, but for starters, from the 1780's on a cravat was made of a piece of linen or muslin 5 feet long by 8 inches wide, folded in half lengthways, then passed front to back, then the ends back round the front and tied in a big girly bow, though by 1800-ish these had evolved into one made from an isoceles triangle 60 inches along the base, 12 inches high in fine muslin, pleated down to 3.5 inches, then centralised at the throat, the ends passed round the back, crossed, and tied in a smaller bow at the front: I don't know for sure, but the second sort looks like the Saint-Just incredibly high but slighly less effeminate neckwear style (he seems to be a neckwear pioneer, as well as giving the world the first Farrah Fawcett hair). These are from an English pattern book, but French fashion was heavily influenced by English at the time.
