[SOLVED] Visible skin lines when clothing is viewed far away

Basically, the issue I'm having is that at a distance, my clothing shows visible seam lines which is kinda weird.
There's no issue in blender, it seems to be an in-game thing. I've tried importing my texture as .png and .dds.
My friend also gets this issue and we're both unable to fix it.

Here's the download for the .package www.sendspace.com/file/3lpd2f
Ignore the specular maps, shadow maps and the fact i haven't done the other lods etc- the dress is a WIP. Also, it's not an issue with the mesh LODs, because the screenshot above was on LOD1 (so it doesn't matter obviously what LODs you're viewing or what LODs the mesh has or whatever) and also other content I've created that have all LODs has the same issue.

Thanks.

EDIT-
it even happens in s4studio too
