Help with lines?

[TomKat93]

I am making a mesh, as you guys probably can see, I am having some problems. http://i51.tinypic.com/x231py.jpg I believe it has to do with normals. How do I go about fixing this, guys? Thanks.

install these, then boot up Milkshape.
select the vertices on the seams and select alligne normals from the menu.

It's really hard to see what's going on with such an extreme closeup. To me, that doesn't look like normals (if the issue is the little darker strip sticking through on the left side) but, well, it could be a few things...

1) Bone assignments, causing two pieces that should be stuck together to have a seam
2) The pieces just aren't aligned properly and need to be fixed in 3D or
3) Material definitions need fixing (if this is an accessory or alpha part): http://www.modthesims.info/article.php?t=202520

I managed to get rid of the line, but the bone weights were so weird that I decided to make a new mesh. I am trying to make a skirt from the butt and legs. I can't figure out how to completely remove the crease from the butt, nor the crease from the crotch area. http://i52.tinypic.com/29xalh4.jpg http://i52.tinypic.com/wkjup2.jpg Edit: I managed to get rid of the shadow under the butt, but I still can't get rid of the creases. How do I do this?
