Crochet for Grandma?

Who said that only grandma wears crocheted wearables? It's an in thing right now to wear crocheted wearable. Even stars also wear them nowadays. Look a this picture on the left. Don't they look fabolous wearing crocheted wearables? I bet it cost very expensive, because as far as I know, there is no machine in the world that can crochet. It's handmade!
