I'm actually modelling clothes for Hiro in Hex too. Here is a WIP.

At the beginning of my learning (i'm still inside this beginning :)) i mainly followed this tutorial.
You could easily adapt it to any other character you want to make cloth for.

I highly recommand you to load inside Hex the Poser character obj you'll find in your runtimeGeometriesDAZPeople. It will come in the zero pose and would be a perfect mannequin to model cloth on.
