So I was thinking, I have skalked around quite a bit and noticed there is not as many things that are fantasy like for Sims in Sims 4 when compared to the amount of stuff that you can find for Sims 3. I was getting kind of sick of looking on my own after not finding anything that I wanted or was looking for so instead I decided to just come here and list the things I am looking for and also things I have found. Hopefully if anyone else out there is having an issue like this they will be able to refer to this and what people have shared.

-Nine Fox Tails.
-Fox Ears.
-Demon like eyes.

For the kimonos and that, on this page you find a lot of Asian cc (especially Chinese because it is a Chinese page :v), for some things you need to be registered but for the majority it is enough that you search well, some upload their cc to baidu and at the end of their post they pass the link together with the password. (Of course for this page it is very helpful to know Chinese or have a translator XD)
Above all I suggest you look well in the messages of jinqiuqiu, he goes up a lot cc in rar in the comments of his messages
barebara2020 also has good cc and you find it in baidu, she/he gives you the passwords in her /his posts
http://game.ali213.net/forum-956-1.html

Reminiscence publishes content in game.ali213, however in its tumblr his/her cc is completely free access

Let me check my cc, I have a lot of fantasy cc, for example the nine fox tails, wings of angel and bat, etc, only I don’t remember which pages I download them from. I'll be editing as I find them
PD: Sorry for my bad English

I am not sure where you are from, but truthfully your english is almost spot on, I had no trouble understanding what you meant so good job! Also thanks for contributing to this list!

Without my Sims 4 Tray Importer I couldn't find the package of the nine-tailed fox that I have in my mods folder </3 (I almost have 25 GB XD). However I found another one, I haven't tried it yet so I don't know what it looks like in the game, but at least in the images looks great!
https://zouyousims.tumblr.com/post/...demon-hair-gold

Ahh I really want a nine-tailed fox for my sims </3 Tried the other you sent but doesn't look very good

Finally I found it!!! I was reviewing the whole page of Natalia Auditore in search of mods that I hadn't seen, and I remembered that she created the first nine-tailed mod for the sims 4:
http://natalia-auditore.wixsite.com...ccs-TS4-and-TS3

Here I give the images of more or less as it seen in the game


I suggest you visit her tumblr or her page, she really is a very good creator ❤

ValhallanSims has an entire line of elf, dark elf, angel and demon developed things -- including faun skin etc. There's gorgeous lipsticks etc as well, and the most amazing horn collection tiered in different sizes so everyone from toddler up can wear them. https://valhallansim.tumblr.com/
I love the stuff I've found there!
