Of course, if you have a skin with every 1.8 feature well utilised, it should be easy to recognise what corresponds to which part.
I got my skin off of Novaskin, then edited it a bit. If I ever want a different skin (per say, one with a swimsuit), I just etid my head onto a different skin. I might make myself a new skin if I ever get around to it, but I'm too lazy. =P
I used to make all my old skins, but as of about 2014 I lost the time, and mostly the motivation, needed to do that. I eventually just found a skin I liked and set that as my skin. Since then I've been putting the face on the clothes of other skins I like. I edited the face last time I changed my skin, so that's kind of my own now
