Her character design has changed significantly from her concept art to here appearance in the Sacred Ashes trailer to her actual in-game model. Her skirt appears rather softer and more tentacular in its earlier incarnation, not to mention the dramatically different shirt.
This goatskin skirt is based predominately off this piece of concept art. The in-game model wears a much neater version, with the dropped belts being much more rigid and regular. The much messier, organic look of the concept art works far better with reality. It did, however, take far more belts than originally thought.
eldritch spear to complete the look.
A set of leather armour for the character Zevran was also commissioned. We may get some photos of that eventually, perhaps even, the new owners willing, some at the convention they're going to.
To commission a similar skirt would cost in the region of £150, though this may fluctuate depending on the cost of materials used.
