Hello, Guys!

I have a problem with many of my dresses and skirt creations being distorted in the center.
I can get most of the dress or skirt to appear correctly (smooth), however the center front and back skirt area usually comes out rough and jagged looking especially when being viewed in game from the side.
I'm not sure if it is a vertex color issue, or those areas are too close to the body or what?
I did try to add the #3FFF00 vertex after #00FF00 and then smoothed vertex colors, but that only helped a little.
I have a whole graveyard of CC that I won't share until I get this issue resolved, so anyone who can tell me what's causing the distortions, your help will be greatly appreciated.
Thanks in advance!
Here is a link to the .blend file for anyone who wants to have a look...
