Assuming you have the modelling side covered, the simplest way to make clothing for Poser 6 is to create dynamic clothing. That sidesteps all the tedious setting up that's involved in making conforming clothes. Max doesn't handle Poser's native scale very well, so it's usual to scale up by a factor of a few hundred (from memory) when going from Poser to Max, and vice versa of course. You should aim to have your clothing drop into place on a zeroed figure when you import it with no boxes checked. This is essential for conforming clothes, and it's a good idea for dynamics too. Roy's Poser Max tutorials are usually to be found in the Web Ring Top 15 (somewhere over there ---->). They cover conforming clothing for earlier versions of Poser, but the general principles are the same. You can miss out a lot of the setting up for dynamic clothing.
