This scene just gets sadder and sadder the older I get.

Small rant time: I hated what they did to her in this movie. She was punk rock and they put her in a dress at the end. She looked horrible and it was clear that the pink dress was not her choice. She transformed due to the attention and she completely changed herself and it always makes me irritated.

She didn’t change herself just her outfit. It was also made very clear throughout that he Andy liked her the whole time. Plus the way it ended with her ripping the patch off his jacket was showing that she was still her and the she wouldn’t change. 

Plus she was wearing a dress the whole movie it was just dark.
