Lauren Conrad married William Tell on September 13th and since then, we've been eagerly awaiting all the deets on this style icon's one-of-a-kind gown. As it turns out, she had three wardrobe changes! 

First, she wore a ceremony ensemble that she collabored on with Mark Badgley and James Mischka. The gown features two-tone Chantilly lace embroidered with Alençon lace appliques. Crystals, pearls and baby glass beads added a dose of sparkle. An intricate illusion back and 10-foot train made the look just as stunning from the back.

In an official statement released by the designers, they reveal that they were "delighted" when LC came to them with her special request. With her young, modern, and sophisticated fashion sense, she embodies the ideal Badgley Mischka Bride. "She wanted a simple and classic yet glamorous gown which paired perfectly with the Old Hollywood element we love to put in each of our designs," Mark and James added.

The bride explains that "I was so thrilled to have Mark and James work on my dress. 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."

For many fathers, the most emotional part of the wedding day is when he walks his little girl down the aisle. One dad made it even more special by singing "Walk With You" by Edwin McCain as he and his daughter made their entrance. What a perfect song for the moment! And the dad's voice is pretty incredible, too. Watch the sweet video:
