Hello.

First up -- most M3 clothing fits M4... pretty good and mostly doable with mnor adjustments for pokethrough (except for things like shoes and socks).

As far as either Wardrobe Wizard or Crossdresser -- they both have M4 plugins that you have to buy seperately. With WW2 -- you have to have both licenses (m3 and M4), while in XD, you only need the one converting to (M4). If you buy Poser 8, it comes with Wardrobe Wizard, but I don't know which licenses/plugins it comes with.

I hope that helps.
