FROM swapping fashion tips to sharing wardrobes, the Duchess of Cambridge and Pippa Middleton are just like any other pair of sisters.

And today, while attending Lady Gabriella Windsor and Thomas Kingston's wedding, mum Pippa seemed to have been taking a leaf out of Kate's fashion book, wearing a headband very similar to one loved by her sister.

Pippa arrived at St George's Chapel, Windsor Castle, with husband James Matthews.

The 35-year-old looked stunning in a floral embroidered midi gown by Kate Spade.

The £695 blue silk style is decorated with the classic Kate Spade flower print, with a flattering draped neckline and puff sleeves.

The mum-of-one teamed the dress with £395 blue suede heels by Emmy London and a £495 blue headband by Jane Taylor - which looks remarkably similar to a style worn by sister, Kate.

And royal fans couldn't get enough of Pippa's look, with one calling her "best dressed" at the wedding.

The Duchess of Cambridge wore a very similar burgundy headband - also designed by Jane Taylor - last year.

Kate wore the accessory on Christmas Day, while attending a church service at St Mary Magdalene - close to the Queen's Sandringham estate.

The 37-year-old's headband is worth an eye-watering £830.

Lady Gabriella is the daughter of Prince and Princess Michael of Kent and married long-term boyfriend Thomas in St George's Chapel, Windsor Castle, in what was the third royal wedding in the space of a year.

Pippa, who married James two years ago and welcomed son Arthur last October, looked happy and relaxed as she arrived with younger brother James.

Also arriving at the chapel was the Queen and Prince Philip, as well as Prince Harry, who took a break from dad duties to attend.
