What are good perfumes?

I am looking for a new perfume to purchase.I want something that is not too strong and smells young. I am a teenager and I do NOT want to smell something like chanel 5. I currently have dolce and gabbana number 3 and brittany spears fantasy. my family members arent such a big fan of the fantasy. I was thinking about buying midnight fantasy,dolce and gabanna light blue, viva la juicy, and MAYBE vera wang princess
