Symbolism
Clothes
Naminé's clothes are the color white, this could be because she is a nobody and their main color is this silverish white, but it could also mean that she is pure, like her other half. Since Kairi was a pure hearted person with no darkness whatsoever, Naminé also has this characteristic. She cannot do wrong because that is not in her nature. White is also not a true color like black. They are just shades for the true colors. This is just like Naminé. She is only half a person. This meaning can also apply to the White Room that she frequently is seen at.
Good Luck Charm
This was only introduced in Kingdom Hearts: Chain of Memories. Naminé manipulated Sora's Oathkeeper charm and changed it into this new one. It made him believe that Naminé was his childhood friend and that she had that ever since birth and was given to him. Even if this wasn't a big item in the rest of the Kingdom Hearts series, it was in the shape of a star, like so many other items in the game. It's shaped particularly that way because stars are far away, but you can still see them like a reminder.
Caged Naminé Doll
Though they only showed this doll once in Kingdom Hearts: Chain of Memories as an introduction to Naminé, it still has its significant meaning. The doll looks exactly like Naminé, and is placed inside a bird's cage. It is a great representation at the time when she was imprisoned by Organization XIII. It shows that she was also like a doll; fragile, yet imprisoned like this doll. She also has wings attached to the doll; as if it represents a locked bird.
