Someone Else's Yesterday

There is a girl who changes how she looks everyday. She changes everything except a necklace which she wears around her neck. One day her hair my be put in a pony tail, the next maybe she cut it short and the next instead of blonde her hair is brown. Changing from boots to tense shoes to heels, t-shirts, turtle necks, v-cut shirts, dresses, skirts, glasses, non, sandals, black, yellow, red, green, blue. She looks like a different person every day, except the necklace. One day someone asked her why she does this. She and she answered, "I'm not who I was yesterday but I am who I am now because of who I was yesterday. Every different style is a new me and my necklace is a reminder of every yesterday I was some else."
