While all eyes were on Kate Middleton‘s stunning Alexander McQueen gown and Cartier tiara during today’s ceremony, guests showed up to the event in some amazing accessories of their own—hats!

From tall and spectacular creations to fashionable fascinators, see the most memorable hats from the Royal Wedding in the gallery.
