Mao's LP dress evolved a great deal. The ruffle around the chest and back kept on getting smaller up until Worlds, and I think they had added new beads that make it sparkle more by Olympics. In the end, at least the cut was good. Mao does look gorgeous in that particular shade of red (like her Scent of Women dress). I liked the SP dress she wore at Olympics more than the other two choices she had, though of course the details were too much up close, but that magenta color harmonized with the vibrant nature of Mao's beauty, I thought.
That said, Mao was not well-costumed this season. Her Claire Lune dress was so sublime! And even the Masquerade dresses from last season were much better.
