All hail the Queen! Queen Elizabeth II is celebrating a very important day this morning: her 89th birthday. Her Royal Highness has had quite a full plate with reigning England since the age of 25—not to mention serving as great grandma to Prince George and the soon-to-be born prince or princess.

Her prolonged tenure has not held her back in keeping up with the times—we've witnessed her hopping on social media by tweeting for the first time, getting acquainted with current pop culture (hello, Game of Thrones!), and experimenting with different monochromatic ensembles. That's right: The Queen is no stranger to changing up her style game. From sky blue hues to pastel yellow shades, see Queen Elizabeth's standout looks through the years.
