Nightgowns are a convenient way to say "I want this to bunch up under my arms as I wiggle around in my sleep to the point the entire thing is half off by the time I wake up." I had a white one just like this as a kid, from a thrift store - it was very old, and I loved its silky texture, despite it being wool! Your sims can love these, too. They were made to somewhat match a few "historical" creations, but not identically - so it sort of fits a vague colour palette that you already have from the likes of Skell or PlumbBobKeep creators.
