I came across this cool clothing creation software. It is a mix of sculpting, cutting, and sewing directly on a mannequin. Much easier to quickly create clothing than just a sewing type application. The exported OBJ files have nice UV's and are ideal for importing and rigging in CC4. The personal use version of Fashion Studio is free. https://audacesfashionstudio.com

Here is a tutorial showing how to export your CC4 character to use as a template, model the dress, then import and rig it in CC4.
