though I am not sure if barovia would use tailoring dummies, the port would have them I imagine though. Of course the port would also likely have people willing to be models too.
I cant see any reason why Barovia wouldn't have them, there is a noble quarter, and even the peasant dresses need to be made up, and a tailors dummie is a tool, its not really a fashion accessory or any such item.
The thing is though, I allways considered Ravenloft to be different to all the other modules out there on the web, and better than by far, because PotM strives to be different. While
ActuallyAgirl has come from a place where you can create a character and roleplay that you are a master/expert of a trade from character creation, doesn't PotM try to avoid that where possible? The master tailors are allready in the world, they are the npc's, and we are the pc's, we have to learn skills and play them out in game. Clothing textiles (as in clothes and armor) are portrayed very differently here on PoTM, you cant just go into a central tailors shop and buy/use every dye available in game, you have to buy them from certain places, and travel to different city's/towns to buy extravagant dyes. The clothes you purchase from the merchant aren't all 1gp each, a gown from Demutriloo (spelling?) costs more than a Barovian peasants dress. There is a certain level of balance in PotM and wouldn't a tailoring dummy risk throwing off that balance?
