My mother was (is) a sibling of twins, and when she had a set of her own -- my brothers, who are identicals somewhere on the path to "mirror" (identical twin development is WILD yall) -- she absolutely refused to give them similar names or to dress them the same. She also refused to call them "the twins".

It was super weird watching as I grew up because some people would just REFUSE to believe she hadn't gone all-in on matching EVERYTHING and also it would've been sooooo cuuuute to match their names (my mother would say "They're people, not a matched set of ponies" with a dead blank look on her face to these people a lot)....and other people would just get this look of relief and excitement, and then start babbling about how wonderful that was.

I always wondered, as a kid, why people seemed so divided on that issue, because there wasn't any middle ground in the reactions.

(My mother did say to me once, "I'm not sure why I bothered making sure your brothers were never treated like a set. I just had a conversation with J, and then five minutes later, the exact same conversation, word for word, with G." I mean, they were still identical twins raised in the same family, mom, they were always doomed to be similar in some ways.)
