Quite a lot of adverse comments have been made of BJ's demeanour and gone through a hedge backwards look, from all sides of the house, not just the opposition.
This lady is free to wear what she likes, but she misjudged what occasion this dress was suitable for. Surely a sign of being an adult, is appreciating what clothes are suitable for what occasion and if you are going to flout the conventions, do it knowingly and with a point. This just looked like a misjudged, got up in the morning and grabbed the narest garment moment.
Every tiny decison anyone makes about their clothes for good or ill says something about you, even if you customarily dress by shutting your idea and putting on the first garment you can find.
