It's that time of year again. Royal Ascot becomes Royal Hat-scot as thousands of racegoers descend for Ladies' Day.
While fans of a flutter must observe a strict dress code, there is still plenty of room for creative expression - particularly when it comes to headwear.
As spectators basked in highs of 18C, they could have been forgiven for being distracted by the head-turning millinery on display.
Ladies' Day is traditionally the busiest of the five-day horse-racing extravaganza.
In the Royal Enclosure hats must be worn, strapless dresses are banned, midriffs must be covered, and trouser suits must be full length and matching.
