I've been searching for hours to find CC that has lots of Alice in Wonderland themes, specifically American Mcgee, but also Tim Burton's version. I can't seem to find any anywhere I look >.< Can anyone point me in the right direction, or is it just hopeless because it doesn't exist?

That's odd -- I typed "sims 2 alice" into Google and got a gajillion hits on the "Image" tab. Here's a couple to get you started.

Adding additional search terms like "american mcgee," "tim burton" or "madness returns" should net you even better results.

I found that first one: it's for TS3, not 2. That second one I found and have downloaded. The third is just a bunch of pictures. The fourth is a pose, not what I'm looking for. And the last two are outfits for the Duchess and Red Queen, again not what I'm looking for. I did type those 3 search terms, and I always get either CC for TS3 or CC that I don't want. I've downloaded the original dress/sim for Alice from American Mcgee, but I'm hoping to find the Madness Returns dresses as well as lots like Alice's house and the Red Queen's castle, the Majestic Maze, etc. I'm having no luck myself.

I also made this upside down house, and gave it a bit of an 'alice' theme http://www.modthesims.info/download.php?t=528906

Oh my god thank you so much *flails* that was so helpful, and I downloaded everything I could find.

Something I wish I could find would be the Majestic Maze and the Red Queen's castle from the Tim Burton movie. But I'm pretty happy with what I have found :D

I have those, thanks Slig.

Also wondering if someone would be kind enough to convert all of Alice's dresses from Madness returns to TS2, because the only ones I found are for TS3 isn't there a thread for that somewhere around here?

All these dresses you will find in the comments, think you will like them http://digitalperversion.net/garden...p?topic=29864.0
