Sorry for the delay. It's been a really long time since I downloaded these mods. I forgot which folders they were in.
IIRC, they work well to create more natural male and female body types.
Delphy breast sliders:
Anderson body shape sliders:
I am not sure how familiar you are with TS3. Those mods will not change preexisting body shapes. You will need to take the Sims back into CAS and use the sliders to change the body shape to your personal preference.
Unfortunately, I still haven't found the mod that gives the males veins and more muscle definition. If I find it, I'll be sure to let you know.
Also, you can try asking for it in the Sims 3 forums. There may be threads for WCIF (Where can I find). Someone may be able to direct you. Please be sure to read all instructions and have fun!
