Theresa May would look a lot better if her posture was improved. I wonder if she has a back problem? She's very hunched, it looks uncomfortable and can't be good for your back. Maybe she needs to do something like Pilates or yoga to straighten up a bit.
Ivanka's dress was a funny one, too casual at the top. Melania needed a bit of bling, she was a bit too subtle. Kate looked like she was being worn by that dress, it was too frilly and fussy. Sophie looked lovely though, that was a great colour on her.
I think the Royals generally looked like last night was one to get through and get home - maybe I'm projecting though!
