They had Lego sets in the 90s that seemed to be designed for girls - the “Paradisia” line. These were like doll-houses (and doll-beaches, doll-horse-ranches, etc. - the sort of places Barbie might go if she were Lego-sized) with tasteful use of pink and plenty of Lego people with feminine outfits and hairstyles.
My sister would get Paradisia sets because she always wanted to do what I was doing, but she didn’t actually like playing with them very much. I would end up putting them together myself along with my robots and spaceships.
