It's the same reason why Luna had an azure mane in FiM Pt.2. They looked different when they were younger, and the Elements' spell returned Luna to a much younger age. My only guess is that they were around Twilight's age when they began to rule, and they did not acquire their flowing manes until they were adults through and through.
