Royal Ascot Day 1: all the most memorable moments!

Ah, the Royal Ascot has finally arrived in the UK. Each year, Britain's finest gather for the annual horse race, where extra posh and extra big hats is the attire.

For those of you not familiar, it's like the Kentucky Derby, except it's five days long and it's akin to a royal wedding what with all the carriages, fascinators and royals in attendance. It also happens to be one of Queen Elizabeth's favorite royal engagements—she has attended every day of every Royal Ascot for the last 64 years.

This year, the British family arrived in true Ascot style for the first day of the annual horserace. From the Queen's arrival to Kate Middleton and Prince William chatting up Queen Maxima and her husband King Willem-Alexander, these are the best moments from Day 1 of the Royal Ascot!
