The mesh is perfect!
So the problem lays within the recolor.
That particular recolor does need 2 subsets, one for the body and one for the barefoot.
So that you can recolor both the robe and feet on a diffrent bmp file.
That way the parts of the robe will not interfear with the feet.
You can add a new subset to any existing maxis outfit(recolor) using this tutorial:
http://www.insimenator.org/index.php/topic,51352.0.htmlIt is a bit difficult(well, you need to focus a little bit
)
If this is complete abacadabra, ill pop one out for you.
Or you use one of my files:
http://www.insimenator.org/index.php/topic,75265.0.htmlIf you take this outfit
*Clone it with bodyshop
*Open that new recolor with simpe
*attache your mesh to it, or make a new.
*change the subset called flipflops into barefoot(its one of the last lines in the propertyset), click commit and save.
*Clone it again with bodyshop and fix the textures.
EDIT,
OH, i had another look at your mesh and you forgot to delete the sexyfeet on the body!!!
Your will need 2 meshgroups, one for the body(without the feet) and one for the feet.
