[OPEN] [GTW] New mother keeps changing in hospital gown

I'm still having this problem. I stopped going to the hospital with my sims literal years ago, but today I accidentally clicked join and now here I am, reminded of the reason why I never take my sims to a hospital. 

Is there, like a trick to remove the gown? Or a mod to do it? It's really interrupting my medieval gameplay. She shouldn't even have had a hospital birth
