I've acquired a lot of budget 'fantasy' wear and accessories from eg Xurge, though mostly for M3/V3 & M4/V4...

I find many free 'Fantasy / SciFi' props, scene-sets and pre-clad, rigged figures / monsters on eg DA and BowlRoll, albeit in XPS, FBX, PMX or SFM format. As Poser_11 can usually manage to import FBX --I'm told _13 is better-- converting to OBJ props or rigged FBX from such 'native' formats via eg free XNA/Lara and free Noesis can supply a  lot of useful stuff. Downside, a clad FBX figure often arrives as many subsidiary rigs. Some will be clothing or hair options, safely deleted. The rest must be promptly parented to first / primary rig lest over-cluttered Poser Hierarchy 'falls over'. Oh, and if FBX does not correctly (*) auto-load materials, that's your evening gone...

*)  Pathing can be problematic: FBX permits both absolute and relative calls to material textures; If absent, set to artist's X: drive and/or deep, deep into folder tree, Ick...
