Any modelling program you like the interface of  can manage clothing. So blender,silo,shade, lightwave,Cinema4d, 3dsmax, maya, modo etc etc .

Hexagon is a good modeller, but the way you do some things I find odd. 

There was also a clothing application that one of the sites was pushing but that was a version of a professional clothing design application. (i dont remember the name)

For the price Philc has to be considered.

All the modellers have trial downloads, so look at a few before you buy. Blender is free, so are anim8or and wings3d.
