Now, That is a great Sim.  Elvis never looked better.

As always...Looking good. Real good.

Can you make a mesh for younger teens?  Male and Female.....without us getting lynched?  Something to fill the age gap between child and young adult?  They wouldn't need to be and maybe shouldn't be fully detailed.

CHANGING SIM'S HEIGHT:
First you need SimPe.... Create or Clone the sim you want to change.  Next...open sim pkg in SimPe.... The default height for a teen, is .94   You can lower this height down to .81 or anything in between.  The meshes that worked at the default size all seem to work.  You can do the same with any age.... And you can change the age as well.  I hope someone finds this information helpful.  
Keep on smiling....................

You do great work.  Thanks...
