I am having a similar issue. My male Sim went into labor of an alien. I traveled to the hospital with my Sim and he had the baby there, but didn't change the clothes before leaving. When my Sim got back home, he was still with the patient clothes, and every time my Sim is supposed to change into the casual outfit, he changes into the patient outfit instead.
I would like to update and reinforce this topic, as patients still leave the hospital wearing a nightgown after being cured, instead of changing their clothes. Game version PC: 1.106.148.1030 . I linked a video showing the action:
