If you can only shop in one place when you're in L.A., come to Fred Segal. They always have the best, up to date clothing for any occasion, for any style. The Santa Monica store is better than the Melrose store, (although the Melrose one is more popular) and make sure you check out each boutique. Also, don't be intimidated by the salespeople. The shoppers may be snobs, but the the salespeople are really nice and helpful.
