Dress is nothing great. The straps at the top and the bit at the bottom look like they were added on - like a dress bought from ebay that's been altered to fit. Having said that she does look lovely in it.
Beatrice & Eugenie look nice actually, Kate's outfit is very boring from what I can see of it. Sohpie Wessex looks nice but why does why insist on these bulky jackets? Princess Anne's jacket is awful IMO, not improved by the gloves either.
Natalie Pinkham looks stunning IMO.
