The Elder Scrolls V: Skyrim for the PC hasn’t been out long, and you’re probably not that surprised that after just three short days there was a nude mod created already for female textures.

The instructions are on the website on how to install the mod.You basically just download the file, and extract the contents into the Data folder inside of your Skyrim installation folder.
The only way to show the textures though is to either kill them and remove the armor or clothes, or to get your pickpocket to level 100 so you can purchase the perk to remove equipped items.
Alternatively you can use console commands if you’re familiar with them, and there are some comments on the site that explain how to do that.
