Mmm I would like some elderly clothes. Teenagers, Young adults, Adults and Elders all have exactly the same clothes. It is cool that all life stages have access to all clothes, but it does cause that all life stages dress the same and that can get inappropriate or not be the look you are going for.
It would be nice if we get some cute elderly-style clothes like long skirts, feminine suits, Granny-panties etc. in pastel colours, powdery colours and florally styles, which is what I associate with elders. Some old-fashioned mens' clothes like overalls, undershirts, bow-ties, snazzy ties, shiny brown shoes etc. would be adorable for those cute Grampies too.
Some elderly hairstyles would also be really cute. A bunch of bun-related hairstyles for the grannies, as well as some elegant bobs and an adorable hairstyle with curlers in.
Come-overs, bald spot hairstyles and other old-fashioned styles for men, as well as that really old-fashioned brown hat that guys always wear in old movies.
These would be absolutely adorable and I hope we get them in a Generations pack. I wouldn't want to buy a SP for it though. But these would be so so cute and make the elders feel more like, well, elders. Partnered with some elderly gameplay like knitting, NEWSPAPERS, special "Granny's cookies" recipe, LANDLINES etc. would make them feel really special. Show the elders some love!
