The dress is a simple skirt with an elastic waist band , with two long panels that double as the top and the capes.
Hopefully this drawing helps explain:
Then the gold pattern was spray painted on with a lace stencil.
The shoulders are a worbla frame with hot glue designs on top secured with craft wire, it is strong enough to hold the capes.
The belt is cut out of craft foam and reinforced with a hot glue layer, then painted gold.
The beads are all polymer clay joined together with craft wire.
