when i camke cloth like jackets the inner part is invisible whats the problem?

 
the question is too vague. how did you make this jacket, what program? the likely issue is the mesh has only one side.

make a duplicated of the mesh, then flip the normals, that will show the inside but not the outside. then merge the two meshes together.

i'm just telling you this blind without knowing much of what you are doing.

i see md means marvolous designer. i don't know much about that program but my suggestion above may be helpful anyway.
