Meghan, on first inspection, I thought she was wearing a dress like Beatrice did to ascot, the central panel made it look like a babygro with the poppers undone.
However, up close the colours were really pretty. As pp have said it’s just an English thing to wear pastels to a wedding. I personally found her dress too dark and a bit casual. It looked like very smart office wear with a pretty hat plopped on top. Slightly incongruent. However being Meghan she looked beautiful. I also loved her makeup; she does it so well. I just think she has done her best to not detract from the bride.
I also have to say how incredibly handsome Harry is looking these days. Especially in the morning suit & dark glasses. Marriage has been the making of him. He always look like William & Kate’s spare wheel. Now he is Meghan’s protector.
