Hello! Sorry for not answering sooner, the email alert for this ended up in my spam. :(

I don't have my TS2 game installed right now but I will do my best on these. Iris's shirt is by Misstiikeri and can be found on her tumblr if I'm not mistaken. The pants are by Yuxi and I believe were in a secret santa gift (possibly the one for me back in like 2012?)

Demi's hair is by Azaya, not sure if it was released tho. I will ask! Both the jellyfish girl picture and I think the human blood poster are also by Azaya! Not shared yet, but shareable! I will ask about those, too. :)
