A royal wedding isn't complete without a bevy of bizarre, gravity defying hats and fascinators.
While the usual offenders - you'll recall Princesses Beatrice and Eugenie's headgear at William and Kate's wedding - went for a more relaxed look this year, several other celebrities stepped up to the plate insome seriously over the top hats.

It's been seven years since Beatrice and Eugenie became fodder for memes with their over-the-top fascinators at William and Kate Middleton's wedding. This time the royal sisters toned down their headgear as they celebrated the nuptials of cousin Prince Harry and Meghan Markle.
While Eugenie, 28, paired her 60s-style dress — a bespoke Roksanda Viola design in dyed teal silk organza — with a simple white pillbox hat by Stephen Jones, Beatrice, 29, appeared to be wearing a multi-strand headband by Fiona Graham with her Gainsbourg dress.
Prince Charles's wife showed up to celebrate her step-son's nuptials wearing an ice pink silk marocain fabric worked in to an asymmetric coat-dress from designer Anna Valentine.
The colour of Camilla's look was neutral, but her accessories were anything but. Her elaborate feathered Philip Treacy hat was definitely an oversized eye-catcher.
