I didn't really think about the color of her outfit until just now. It's white, which is the color of innocence and purity. The hair being down and flowing is also something that can indicate purity. Flame Princess is a complete innocent, both in what happened in Frost and Fire and just in general. She was trapped in a lamp most of her life and was counting on Finn to tell her what was acceptable and what was not. So his betrayal of her goes far beyond just manipulating his girlfriend. He manipulated an innocent soul into doing something bad and convinced her it was the right thing to do.
