And last, but by no means least, Her Majesty herself rocked one of the best looks of all the guests. She proved at 92, she still has plenty of fashion game.
Eagle says: "The Queen looked amazing - it was a really fun colour. It made you feel like she was looking forward to the wedding. It was an almost florescent dress with a very vibrant purple to it. It really shouldn't have worked but it absolutely did."
Von der Holtz points out: "The Queen is usually in monochrome - so a big bold print dress under her coat was really unusual. She looked relaxed and positive about the day.
"The whole thing being in Windsor felt a bit more relaxed than previous occasions. It felt really happy and joyful and not too ostentatious."
