I liked the shape and idea behind the wedding dress, the high neck looked fresh and modern, but the choice of fabrics ( heavy for the dress) and then as pp said the collar looked like an afterthought.
It was all rather Puritan rather than festival.
Cressida looked a right mess; work jacket and beach espadrilles. It’s only because she is young and pretty that she gets away with it.
Nobody looked good at that wedding. Katy Perry looked promising till you saw the unicorn coloured dress and cheap looking shoes peeking out.
