Little was known about what Lauren Conrad wore on her wedding day, until now! The star's long-time hairstylist, Kristin Ess, posted an Instagram photo of the gorgeous bride and her handsome groom, William Tell, from their big day—and as expected, Conrad is the picture of perfection. Looking every bit as romantic and beautiful as we'd imagined, her custom-designed Badgley Mischka Couture gown features yards of lace and a sheer embroidered back. The lifestyle guru completed her ensemble with a sweeping tulle veil attached to a sparkling headpiece. Stunning!

"I was so thrilled to have Mark and James work on my dress," Conrad said in a statement about her one-of-a-kind Badgley Mischka ensemble. "Not only have I been a longtime fan of their designs and aesthetic, they are also the nicest guys. They were so sweet and made the process really enjoyable. I love my dress."

The former reality star, 28, said "I do" to her longtime love, 34, in a rustic-chic ceremony in Santa Ynez, Calif., on Sept. 13 with a multitude of family and friends present. It was previously revealed that Conrad designed a collection of 12 bridesmaid dresses for her clothing line Paper Crown that her maids wore during the ceremony, though we have yet to learn more details about the nuptials—stay tuned!
