John Doe - Clothing - Vest
NO Shape Keys to morph the vest to different shapes and sizes but, it easy done by creating a new Shape Key and adjust the vertices in edit mode to your characters build.
multiresolution is subdivided by 4.
Texture alpha's are sculpted on to the model > cotton and creases are done by hand.
Retopologize the character, when its complete with clothing and bake from high poly to low poly to achieve a low poly character model with high level of detail.
