His way is much more simple than what I was doing
Either way he was having the same trouble I am. For example: I currently use the Epic set and I want to use the Halloween Set. Since the Halloween Set is divided into parts, body, leg, boots, gloves, this is good because you can easily rename the skins for each part. Halloween boots skin renamed into Epic boots skin. Giving you Halloween boots while wearing Epic boots.
But some sets only have a body file which contain all parts. So when you equip only the body you get: texture glich (notice the feet, legs and thighs.
To fix this I made the legs, thighs, arms textures blank. Therefore nothing gets overlapped with the body texture. However if you don't wear any body suit/dress, you get:
Either way here's what you asked for. I can't get set #2 because I'm only using NA version. That's from the CN section. If you or anyone else has ideas to fix this problem, then great, share
Again, if you're not wearing the entire set it will look weird/invisible. (You can mix and match rare/magic though, no prob)
