We love a British wedding. From Prince William and Kate Middleton's Royal Wedding to Kate Moss's rock and roll nuptials with Jamie Hince, those posh Brits know how to put on a party.

The latest in our Anglophile obsession is Poppy Delevingne's wedding to longtime boyfriend James Cook. Poppy, a model like her social media phenom sister Cara, wed Cook earlier today at St. Paul's Church in London.

Both Poppy and Cara stunned in custom Chanel Couture dresses. Poppy's flower-and-bead encrusted wedding dress is strikingly similar to the Chanel frock that Blake Lively wore to the Green Lantern premiere in 2012, when she stepped out with Ryan Reynolds. Both have flowers dotting the bodice, distinctive cap sleeves, and sheer skirts. Poppy's, however, is totally bridal thanks to her flowing veil (and perfect blonde waves).

Cara, who served as maid-of-honor, pulled a Pippa Middleton and donned a floor-length white Chanel gown with a flutter detail on the neckline and sleeves. We love her simple bun and awesome shoes! Poppy and Cara's father Charles looked dapper in his suit; he walked Poppy down the aisle for her big day.

Sixteen (!) other attendants served Poppy; most were adorable flower girls who wore flower crowns and white dresses. British weddings often feature bridal parties like this — both Middleton and Moss had a gaggle of flower girls. But perhaps our favorite part of the younger crowd was a little boy who wore a bear suit as he walked down the aisle.

For his part, Cook wore a formal gray suit, complete with a morning coat and a blue tie. Guests included former Spice Girl Geri Halliwell and composer Andrew Lloyd Webber.

Ever the supportive sister, Cara shared a sweet Instagram of the wedding invitation earlier in the day, with the simple caption, "The big day".

Everything about this event is simply beautiful, and the pictures are obviously gorgeous. Congratulations to the happy couple!
