This is a 3D model of a jacket, 301996 traingles normal version and 1176276 triangles (591357 faces) subdiv version.
Model in blender file is not tringulated.
It has different material slots for each part, so you can easy put your design on it (see example pictures).
Trims, zipper and collar have UVs for tileable textures; front, back, pockets and sleeves for non-tileable.
I added a texture for zipper, for better understanding how it works.
Seams and zipper metal parts are also UVd, but they need just a solid material.
The jacket also has second UV channel with all parts in one atlas, in case you'd like to texture it.
