Royal Ascot 2013 has officially kicked off with big hats, fancy frocks and a nation waiting to see if any celebs break this year's official dress code.
While the Queen opened the races with a fetching baby pink ensemble (do we see some Kate Middleton inspiration there?), Katherine Jenkins (of course) brought some colour to Day 1 with a zingy tangerine dress and fuchsia pink hat.
Looking forward to seeing what everyone's wearing? Here are a few to get you started...
