How would you say "my name is Cosette" in Japanese?

Question:

i want to know how to pronounce it not write it. my name is pronounced Co-zet.

Answer:

1)Watashi wa Kouzetto desu. (I'm Cosette)
2)Watashi no namae wa Kouzetto desu. (My name is Cosette)

These two would be the main examples of basic "My name is...." sentences :)
