I use 3D Max to model the clothes. Not to bash PhilC's creator but it's not really for creating professional clothes. It is really great for tossing out a quick dress or something though.

To make pro level clothes you need a full blown 3D Modeling app. Hex would certainly do the job and since DAZ has it on sale for $2 (yes you heard right TWO DOLLARS) for Platinum Club members now would be the time to pick it up.

Two bucks! Good grief! I don't even need it and I bought it. Who knows there may be some goodie that it does that my prehistoric version of Max doesn't.
