What are those gowns?💀 The corset for posture then this huge padding is just a recipe f...

Thats actually what used to be worn back then even irl
Some reports even say that some women's organs would shift due to wearing corsets for an excessive amount of time

that's some bs, corsets were actually much more comfortable than modern bras because they balanced the weight on the whole torso and not just the shoulders. corsets were literally worn by women working everyday jobs, they were pretty comfortable and actually helped balance the weight of the dresses they wore too.

also, most likely, a dress this big wouldn't have that many petticoats underneath it to keep it poofy, it would most likely be some kinda crinoline structure with a padding from the back. sure it wasn't like super comfortable at all times, but it's similar to discomfort modern women deal with when they put on uncomfortable but beautiful dresses to big events

Okay thats crazy i was a bit out of proportion but corsets back then weren't comfortable
Most women back then wore them tightly depending on the fit and it would cause discomfort, shallow breathing, and back strain.
And actually, Organs did shift, but temporarily
X-rays and preserved medical specimens from the 19th century show that tight corsets could compress the rib cage and push some abdominal organs slightly upward or downward. Ppl who wore it more often had more "long-term" effects but those were kinda rare
But you're right about the working women part!
Working-class women often wore looser ones that allowed movement, while wealthy women aiming for a 16–18 inch waist were more likely to experience health effects. (Which we are talking about here since Courtney is not a working woman but a "wealthy" lady looking for aesthetic rather than functionality)

I was kinda exaggerating in my first comment, organs did shift but not in the extreme ways i made it out to be
The most extreme case was women fainting of overuse (fun fact: fainting couches in Victorian homes were a thing and were also partly a cultural trend)
