Gap and slit hole in mesh

Hi there,

I have a gap in my mesh issue. There is a slight hole from the band to where the skirt flows out. Plus the fornt of the skirt has little gaps. This is ONLY for LODs 1 - 3. LOD 0 is perfect.

Here is what it looks like in LOD 1. It's pretty much the same as LOD 2 and 3, just that they have a few more.

I have tried joining them manually but nothing is working. Is there another way?



Here is the file:

Thanks so much! I have been learning tremendously with this forum <3
