The pair have been dating since 2012 and announced their engagement last year via a notice in the Times - and ever since then we have been excitedly waiting to catch a glimpse of Leslie's wedding dress.
The 31-year-old beamed as she stepped outside of the car with her father, in a vintage-style Elie Saab lace dress. Leslie opted for a classic fit-and-flare cut, sweetheart neckline with long, sheer sleeves.
The ivory dress was covered in delicate lace and is from the Elie Saab Bridal Spring 2017 collection. Leslie's hair was worn in a short bob with soft curls and she wore a flower crown on her head with a long, simple veil covering her face as she entered the church.
Elie Saab are known for their fairytale-esque dresses and Rose's dress is no different. The intricate lace interwoven with stunning embroidery and flowing into a full skirt is the tried and tested fit that Elie Saab fans love.
Leslie's Game of Thrones co-stars, Emilia Clarke, Sophie Turner and Maisie Williams all looked impeccably dressed with Clarke in a patterned blush-coloured dress and pink coat and Williams and Turner matching in co-ordinated red and black outfits.
After the ceremony, the wedding party relocated to Wardhill Castle - the estate owned by Leslie's family - for the reception.
Congrats Ygritte and Jon, erm, we mean Rose and Kit!
