Leighton's look might seem silly, but in all seriousness, she decided to take a risk tonight, and that's what the Costume Gala is all about (did you see Madonna?). So I applaud the effort. She really tried to match her overall look to her costume-y ensemble, and for that she succeeded. Knowing that this is an extravagant gala, are you liking her look? Or do you prefer Lively?
