Kate Wore a Real Conversation-Starting Headband to Prince Louis's Christening

Today, Prince Louis is being baptised at the Chapel Royal at St. James's Palace, and he was carried into the chapel by the Duchess of Cambridge, who's wearing her go-to designer for special occasions, Alexander McQueen. She wore an ivory dress with a deep-V neckline, puffy shoulders (reminiscent of the silhouette Princess Diana often turned to) and a fluted skirt. This sleeve detail is one Kate's particularly fond of this year—at the Trooping of the Colour, she wore a pale blue dress with the same pronounced shoulders.
