This was a custom mask made to go with a quinceanera gown. It's a stick mask layered with pearlized paints, silver trims, white feathers, and an ornate bed of pearl beads, and rhinestone centers.
This is an in-progress shot of the mask where you can see a lot of the details close-up.
Later on, a few more things were added to the mask with a color change to white and gold. The silver trim came off. The mask was embellished with gold glitters and gold trims.
This is what the final looked like. Really the mask could have gone either way. Earlier pictures of it as a white and silver mask to this where it became a white and gold mask.
