Hi
When I import my collada .dae file for instance into Blender, everything is there, clothes colors and body.
When I import the exact same .dae file into Unity, I only see the clothes but no body, just clothes hanging in the air. So I guess I need to do something a little more?
I have tried to export to fbx, and then import that to unity, but still there is no body 
Are you certain the normals for the body are not inverted?
Thanks you might be right. Sorry if my qeustions are basics, but I am new to both 3D and Unity.
Could you please explain further…?
The importer in the inspector menu, under Normals I can set it for import or calculate. It does not seem to make any difference…
After some time with Unity I finally saw the error message in the buttom left corner (sorry, but I had excepted it to pop-up). The case is that Unity has a limit for polygons (triangles it says) of 65000. If you make your own model, the simpel solution is to just split it up.
(In my case unfortunately this was not possible, so now I must choose to either to use a low poly figure, that is lower quality, which have consequences in my case, or to leave Unity and use another 3D program).
Oh, I don't know then. If you don't want to go low poly maybe you should look into UDK.

For future reference if you dot have a solution just add a comment(bottom left of each answer). I meant the normals for your model so if you use blender you would have to invert the normals for your character. If you are still confused trying searching google a bit or I could try to explain better. However, I myself am mostly a programmer so I know only the basics of 3D modeling.
