While corsets weren't inherently restrictive unless someone was wearing them incorrectly, sleeping in them was another issue entirely.
Leonor woke up hardly being able to breathe as the heavy dress she wore along with the corset and chemise underneath constricted her abdomen and chest. She sat up, gasping for air and wondering how long she must have been breathing shallowly to make herself feel so lightheaded.
However, as she opened her eyes slowly and realized that it was early in the morning, the room seemed to spin and she felt nauseous almost immediately.
How could she forget the state in which she fell asleep?
While she was drinking, she didn't even notice how much she consumed until she stood up. Falling into Desmond should have been her first warning. She was so embarrassed at how out of control she felt.
