This ridiculous get up is another case of her getting it totally wrong. As discussed on here before, genuinely wealthy "old money", public school, eccentric country types never over-dress. If anything they wear pretty simple, plain clothes. Probably good quality, or things handed down in the family (in the case of jewellery, watches, bags) but dressing in a "costume" like this to fit in with the occassion screams chav!!! Also, what did Coco Chanel say? "Before you leave the house, look in the mirror and take one thing off".
