It's probably not real but I have seen people with psychosis that behave similarly. It sounds funny but for the relatives it can be really stressful and sometimes horrifying. Not because the patient is violent (although that can happen too of course) but strange behaviors and beliefs that can't be changed or challenged.
Although I've also seen a few people deal with it through humor
I'm actually quite interested in dress history. I'm an engineer at heart and clothing is fundamentally also an engineering problem (and design of course). It's an area of engineering that was always dominated by women and you can sometimes see the novel approaches that brings.
For example historical corsets were actually quite comfortable when fitted right. One reason why is actually breast support. Predecessors to the modern Bra did exist but were not in fashion as a more compressed looking bust and later a shaped silhouette was in fashion.
Also it's cool what tricks one can use to form the silhouette without extremely compressing the waist (which is how many modern people often think is the function of a corset).
