I'm not sure this is Chandelier Helm. See post #5838022

• The neckline goes much lower
• It is held up not by straps, but by thin gold chains.
• She is wearing a golden choker with dangling blue gems, not a pearl necklace
• There is some kind of blue and gold ornament on her left side, above her hip, which is nowhere to be seen here.
• This dress appears to be mid-thigh length when it should reach her feet
• At the very left edge of this picture, you can see a triangular hair ornament with a chevron on it. Helm has these in her base costume and her Aqua Marine costume, but not in her Chandelier costume.
