As a woman that has worked on a farm, I know the importance of having movement and the women in Outlander are no different. The toil on the farm required one not to be bound by their clothes. Yes, I know there is the corset issue but that was the 1740s solution to breast support. The skirt design of the time period was full enough to allow a woman to ride a horse without clothing restrictions. On the other hand though, the jacket that was commonly worn over the corset could be tight and I am speaking from experience. This snugness was a necessity due to the fact that typically the only closure was a lacing up the front, which made the jacket adjustable to many different sizes along with holding the stomacher in place. While not much could be done about this restrictive nature of the jacket around the corset, the sleeves were another matter.
While Claire in her 1940s life used laundry soap and a basic washing machine, her time traveling life did not have such a luxury. Instead, wash day consisted of lots of drinks, hand washing, and urine production.
