I love the name Scarlett, I know one who is a very confident, chatty, strong willed little girl who does not do as she's told! She's gorgeous though!
Only downside is that her name is shortened to Scazz, which I HATE with a passion. We've started to shorten it to Scampi (or Scamp) which suits her personality down to the ground!
But I suppose it's not a problem if you really don't want to shorten a name.
