Pearl specialist Bradby, who attended the royal wedding with her husband Tom Bradby has nothing but admiration for the Queen and her sense of style over the years. "From a stylish young princess to one of the most revered and respected states persons in the world, the Queen has never put a sartorial foot wrong," says Bradby, who says she particularly likes the monarch's "practical side – heels never too high, gloves for warmth, a hat brim never too wide."
