Pippa Middleton and James Matthews' wedding day is finally here.

The 33-year-old bride stepped out from a vintage car at St Mark's Church in Englefield, Berkshire with her father, Michael, wearing a custom-made gown made by – you guessed it – British designer, Giles Deacon.

The high-neck gown mirrored that of her sister Kate's wedding dress in 2011, featuring a lace neck and open back, with a train that cascaded down her back.

The bride also wore what appeared to be small, pearl-drop earrings by jeweller Robinson Pelham, and a small pearl-trimmed clip in her up-do.

The bride smiled at paparazzi and fans awaiting her arrival at the church as she carried a small cream bouquet of flowers, minutes after her page boy and flower girl, Prince George and Princess Charlotte, prepared for their leading roles down the aisle.

Prince George – who wore a white Peter Pan shirt, khaki silk shorts and cream shoes – was spotted helping his younger sister, Charlotte, hold her floral, heart-shaped wreath.

The two-year-old princess was seen dressed in a cream dress with a large blush pink bow fastened to the back to match her shoes.

Pippa's sister, Kate, soon made an appearance outside the church, helping the group of pageboys and flower girls prepare to walk down the aisle ahead of the bride.

The Duchess of Cambridge wore a blush pink, long-sleeved Alexander McQueen dress for the occasion, with a matching fascinator, as she smiled at onlookers and helped her sister with her train on entering the church.

The mother-of-two originally wore a McQueen creation – designed by creative director, Sarah Burton – for her own nuptials to Prince William in 2011.

Pippa's arrival at the wedding came minutes after guests including the likes of Prince William, Prince Harry, tennis player Roger Federer and wife Minka, Princess Beatrice and soon-to-be brother in-law, Spencer Matthews entered the church.
