Character Development in blender 2.5 book help

Hi guyz. I have followed the Jonathon Williamson Book character development in Blender and i have completed the blocking all the cloths,the body and the accessories. But my accessories and clothing does not fit nicely on the body. Rather they sets very badly on the character. So the question is will i be able to settle this issue after i sculpting details or i have to put these accessories nicely on the character in blocking.y Progress so far. I have not modeled the backpack yet due to some reasons.Forgive me if i am posting it in wrong section and by the way thanks in advance.
My progress so far
