That's the name of a maxis mesh - which is what the mesh was probably cloned from. Unless the creator decides to change the resource name (not even sure if it will work properly), CC meshes will always have "maxian" names in the resource files.
Try this one. Closest I can see fits to the outfits you're trying to download. If it's not that one, look for another outfit with a mini skirt.
