Thank you! Yes, it was done in Poser 7,they are having a sale at Smith Micro/Content Paradise now and you can buy it for around $40 US. Also there is Daz Studio which can use Poser items and you can get for free at Daz 3D.com. I have both but mostly use Poser 'cuz that's what I'm used to, each program has it's own unique features so a lot of people use both, depending on what they want to do. The clothing came from two sets I bought at Daz, WoodGod for M4, which has the belt/sash (yes it's part of the belt but you can adjust the length or even make it invisible) boots and gloves. The chains and leggings are from the Mourning Sun outfit, very Goth and sexy.
Oh yes, that cage gave me some very wicked ideas as well. Snape is in for quite a workout when Harry finally catches him. ;-)
