With social networking all the rage as the successor to forums, new sites are opening up all the time. Here’s one for the beauty and fashion enthusiast.

It’s called Lookspark and, if you’re quick, you can win an Apple iPhone.

LookSpark is an online fashion and beauty community still in beta, but already 30,000 people strong. Members dish on the latest fashion trends, share beauty tips and fashion wisdom, and connect to the newest designers, boutiques and fashion events. LookSpark “MatchUps” allow community members to vote on today’s fashion and beauty trends. It’s free, and it’s a fun place to gossip with like-minded fashion friends.

Also, if you post an opinion (called a “Spark”) about the designs, models, or the events, you become eligible for a chance to win an Apple iPhone (contest ends September 15).
