Enayla's Pixie skintones (6 human, 4 fantasy) linked to both athlete (as normal state) and slim bodybuilder (as fit state).
Because scrolling through pages after pages of catalog items is not acceptable =P.Each skintone is linked to both body type, to toggle in between, just have your sim go from normal to fit or from fit to normal. **Keep in mind the difference is only shown when the sim is not wearing anything, such as when showering. You do have to buy specific and seperate clothes for each body type.
For a more detailed preview of the skintones, see
Enayla's section.
