You should almost always start in pose mode and then finish with proportional editing if possible, sculpting if necesary.

Scaling the armature will move everything, not just the vertices. For example if you edit a shoe to be larger and it has laces weighted to a physbone then you will have moved the mesh off the bones which will fuck it up. If you scale the shoe in pose mode the child bones and weight paint will update to match.

Pose mode also scales all the meshes at the same time and will keep their weight paint consistant, whereas you can only sculpt one mesh at a time.

Pose mode can also make use of symmetry even if the mesh is not symmetrical, which is not true of edit mode.

If you are doing this it is often useful to set Inherit Scale to None at certain points in the armature to limit the effect your changes have. This is done in edit mode.

Never press CATS "start pose mode" because it will reset the pose to default, undoing any work you have done, until you have applied it.
