I dont think their aesthetics are similar, maybe a little
But they both seem to be quite active on twitter, might have had beef though because of some fish thing? Not 100% sure
What do other people think about her sister Creamicloud? I still believe she isn't real and it is just Milkimind with some good editing skills https://www.instagram.com/creamicloudxo/
To me it's obvious that they are real sisters.
e.g. on the account you linked there is a stories highlight where those type of questions are mentioned.
This account of Milki https://www.tiktok.com/@milkiwifey there are multiple videos of them just hanging out, (don't want to directly link as I fear it might be against TOS)
Milky was teasing something like she would put a real fish in her.
Then some thot called sarahtonin wrote on twitter how disgusting put a fish in you bla bla
They had a beef about two weeks long
In the End milky just ate a fish.
