Pippa's dress looks very nice but those espadrilles kill it. There's far too much black ribbon flapping around.
James Middleton - at those trews!
Sophie Wessex's dress is ruined by the black bits on the sleeves imo. It's too busy a style for Wimbledon. Also, I think she wore the dress to Ascot, or one very similar (I remember those sleeves from somewhere).
Pastels and black is not a good combination.
Camilla looked nice - simple dress with few busy details, colour that suit her - the polka dots make it summery and relaxed, but those nude pumps ...
I like the grey dress that MM wore but she should have had a smaller bag or a clutch. A little boxy handbag would have been nice. The big bag looked too officey - as if she had her shoes for running to the train later in there, along with her lunch and her yoga stuff and bottle of water.
The neutral/muted colours look really good on MM imo, and I include in that category the oxblood leather jacket she wore at the Invictus Games. Bright colours would completely swamp her complexion. Also, British people in general seem to have a taste for bright, bold colours whereas Americans (American women anyway) tend to go for more muted tones. In the US, muted, subtle colours are a class marker.
