Princess Beatrice channeled SJP at her cousins wedding this weekend wearing a great bright coloured fascinator. She teamed it with an Alexander McQueen dress which we've now managed to track down! The silk dress is part of McQueen's summer line but it will set you back £1,085. It features a gold thread-through belt with the length just covering the knee. Beatrice wore it with metallic heels.
I don't know if McQueen = wedding appropriate
