While last night's state banquet was quite the formal affair [1] — Kate was dressed in a long gown and the Lotus tiara — today's events called for a shorter hemline. But that doesn't mean the duchess looked any less elegant than usual [2] when she stepped out in a Dolce & Gabbana guipure design.

Kate chose the lace number to greet Chinese President Xi Jinping [3], his wife, and actor Jackie Chan! Practicing their signature style move [4], William matched his plum printed tie to Kate's deep-purple dress. Kate provided subtle contrast to her look with cranberry suede accessories, including a clutch and pumps, and she finished her outfit with diamond drop earrings and her sapphire engagement ring.

But we've got all eyes on the foundation of Kate's look — that high-neck cocktail number we'd wear to any upcoming party. Read on to see Kate work it from a few different angles, then shop it below!
