How to fix a misaligned Torso?

Hi! There's two types of content, painted onto the skin content and actual clothing meshes that go over the Sims' body geometry. You're recoloring a mesh that falls into the second category. recoloring its texture isn't going to change the shape of the actual mesh, that's done in blender. what you should do is clone another item that's painted into the skin and import your new texture there. you can clone the tucked in base game tank top.
