For any bride-to-be, one of the most important pre-wedding commandments is to avoid beauty treatments right before the big day. While it may sound bizarre - a facial might cause a breakout while a haircut has the potential to end in disaster.
Princess Eugenie decided to set her own rules, making a major change to her appearance before her highly anticipated royal wedding.
The 28-year-old stepped out on less than 24 hours before the nuptials with freshly dyed locks. She is set to wed Jack Brooksbank at St. George's Chapel, Windsor Castle on Friday, October 12.
Eugenie (the first cousin to Prince William and Prince Harry) was seen in London with a brand new auburn hair colour.
We can't help but be reminded of another auburn-haired royal bride - Eugenie's mother Sarah 'Fergie' Ferguson, The Duchess of York. Fergie wed Prince Andrew at Westminster Abbey in 1986.
