>Did Luna NEED to have each & every cycle of the moon on her dress, Sunny NEED a sun at the end of her long sleeves, and Star NEED stars on her dress? No, but it's neat.
How much of those are actual ZUN concepts and how much of it is just Hirasaka adding embellishments for the game, though? They don't have those details in most of their appearances.
I know the moons were in a 2008 ZUN drawing, at least, but I've never seen anything as far as the other two go.
