There are twenty garments total; there are catalogue shots below. Each of the four basic archives contains one of the four styles of skirt. Within any given archive, the individual garments are: (First)
: The base, without dirt. (Second and third)
: For each of two colors dirt (dark and light), a dirty version that also projects dirt onto the Sim's top in the pattern of a V-neck tee shirt. (Fourth and fifth)
: For each dirty skirt, a still dirtier version-- with dirt in the same places, but more of it
-- that also projects dirt all over
the Sim's top.
The V-neck dirtying versions will work with any top with fabric in the places corresponding to the Maxis teen tee with a V-neck. There are a variety of these, in various sizes, available at http://www.modthesims2.com/showthread.php?t=241279
The everything-dirtying versions will work with most Maxis or Warlokk simple tops-- but not the halter meshes, for no reason I can fathom. Here, the models have changed into a variety of tops from the base game or available at www.modthesims2.com
The fifth archive, CreatorPNGs_dirt0A-tsb4_dirt0B-tsb9.zip , is for creators desiring to make their own dirt-projecting bottoms on the base game SkirtUBoots mesh and/or "the mystical one"'s Warlokked versions. It contains no garments-- just .png files and documentation summarizing how to make use of them in a layer-capable image editor (such as Photoshop or The GIMP.)
Your eyes do not deceive you: the meshes' uvmaps use the same parts of the files for both boots, forcing them to be perfect mirror images.
Please do not upload this stuff, or anything derived from it, to pay sites. Note particularly that "derived from it" clause; no building a dirtied or dirtying garment using one of these textures or alphas and putting it somewhere people have to pay to get it.
