This mod replaces almost all the upper leg, upper arm, belt, lower torso and upper torso armor textures with transparent ones (female and unisex ones). This means that almost all the female player characters will now appear nude (the ones that don't use some skins from patch files, can probably be fixed, but it's not very common). The main problem with it is that quite a few textures are also used for male player characters (it's possible to fix this).
To use this, it's best to use Azerothica's modified
WOW.exe (get it here:
http://azerothica.com/downloads) so that you can simply place the MPQ in the
Program Files\World of Warcraft\data folder. Some possible names for the the MPQ are:
wow-update-base-15594.mpq
wow-update-base-15051.mpq
wow-update-base-15052.mpq
You can also place it in
Program Files\World of Warcraft\data\cache and name it like one of these (thanks to Zilem):
SoundCache-patch-15211.MPQ
SoundCache-patch-15354.MPQ
SoundCache-patch-15595.MPQ

WOW.exe for them to work, but most people already know this.
