Tsukino Usagi (Princess Serenity) wearing Dior's Palladium Dress.

The design of Princess Serenity's dress was inspired by Palladium dress and the design of this dress was inspired by the Ionic columns. 

Actually, the column should be much larger, but I reduced it as I wanted to depict it so that the column would fit on the drawing without increasing the size of the image.

Sorry my english is not very good^^
