the kelly set you showed is either a variant or missing a tiny little piece which is a white bow on the cute little blanket she has over her crib. As for the melody doll (my favourite) she is part of the "lil friends of kelly" collection and she is a bunny melody missing the bunny ears headpiece. Everything is really cute, 90s barbie era is my favourite era of all time! I'm in my 30s as well, still have most of my barbie dolls from my childhood but during the first lockdown in 2020 i started collecting barbie dolls (and other dolls) as a hobby! It's such a beautiful hobby, even just combing their hair or looking at them
