Someone else was making the argument that Tiana not being seen in either iconic dress in the finale was a miss for the Princess angle. Another poster then said her outfit doesn't matter as she's still a princess in the world of the character, no matter what she wears. I was simply responding to that point that her princess allure is tied to iconography rather than any aspect of her character. She's not living in a castle or acting "like a princess" in a fantasy aspect. It is the dresses she wears when mistaken for a princess and at the end when she becomes a princess that cement her as a princess in the eyes of many consumers.
I don't think her dress is SUPER important. But I was in disagreement that it isn't important at all, and that's why I responded as I feel, based off the information provided, her dress does hold some importantance in how the character is viewed and remembered by consumers.
