Some body skins also use an Alpha Channel for no reason, and DTX3 or 5 will include that channel as part of the image, even though the skin doesn't need it. Usually when I start a skin (if it has a template) I'll look at the Alpha channel and if it is all black or all white I'll just delete the channel, and that's going to be a little bit of data saved. And as James says, changing the method of DDS export to a higher compression value will usually do the trick. Another thing you can usually get rid of is things like Gloves or Helmets or Crew skins. If those aren't present, you will just use whatever the default for those items are.
