Art nouveau, if you can't tell. Kind of. Probably not adhering to any strict design rules here, but yeah. Flowing cloth, pretty lady, shapes... What little girls are made of!
Anyway. I always thought the 'simple shape with cool textures or patterns or images inside it' was really awesome, so it's in her cloth. And the tiger stripes. And everything's blue. Except for the things that aren't blue.
Five-or-six colors on navy.
