The Duchess of Cambridge looked radiant at the state banquet for the visiting Spanish royal family on Wednesday in a plunging pink lace Marchesa gown, but it was her accessories that really stood out. Middleton chose one of Princess Diana's favorite tiaras for the occasion and added on a statement diamond and ruby necklace from Queen Elizabeth's collection.

The tiara was actually a wedding gift to Diana and remained one of her favorite pieces of jewelry.

The duchess wore more makeup than we're used to seeing on her, including a pink smoky eye and a peach-toned gloss.
