For now I'm done with porting clothes so I decided to put together this overview for future requests.
Molly's outfits F, G and H are unused ingame
Sadie's outfit G is unused ingame (I also don't remember her D and F outfits being used in the story but I can't say for sure)
For Abigaii's outfit H I tried to recreate her RDR1 clothing
For some reason Susan has an unused corset. No idea in what scenario that would have been used
Update 01/21/25: Added two more unused Molly outfits and one for Susan
