The Bride Wore Oscar de la Renta—Then Changed Into Cowboy Boots—To Marry in Her Hometown of Dallas
Interior designer Rosemary Miller first laid eyes on William Spiller when she was on vacation with her family in Sun Valley. “We were having lunch at Will’s father’s wine shop, and he happened to be working there on his college break,” Rosemary remembers. “I looked at my parents and said, ‘He’s really hot.’ It wasn’t until about five years later that he realized I existed.”
In the summer of 2018, Rosemary left her job working for Mi Golondrina in Dallas, where she grew up, and moved to Sun Valley for a summer before returning to school to study interior design later that fall. “I was taking a golf lesson, and Will happened to be there and came up to my instructor and introduced himself,” Rosemary remembers. A few days after that, they crossed paths at the watering hole, The Cellar, and hit it off. “He kept asking me on a date—I was nervous to accept thinking it was just a summer fling,” Rosemary explains. “But at the end of summer, I went back to Dallas, and we dated long distance for two years before I finally moved up to Sun Valley.”
“I distinctly remember watching Rosemary arrive for that golf lesson,” Will remembers. “She was in the most perfect all-white golf outfit. She walked by me to go take a lesson with the golf pro, Dom Conti, who also happens to be a friend of mine, and I turned to my co-worker and said, ‘Who is that?’ to which he replied, ‘You don’t have a chance!’”
The couple got engaged the night before Thanksgiving of 2023. “After dating for over five years, I was really hoping that an engagement was in my near future,” Rosemary admits. “Especially since my family was coming for Thanksgiving. But Will is very sneaky and tight-lipped, so I had no idea when it would actually happen.”
When Rosemary got home from work that evening, she and Will were planning on meeting her parents for dinner, but Will asked if she wanted to walk the dog beforehand. “When we got to the river, I was like, ‘Oh my gosh is it about to happen?!’...and then it didn’t,” Rosemary remembers. “We got back to the house, and I was in my closet secretly bummed out about the whole thing, and then I turned around, and he was on his knee. It ended up being the best surprise ever in debatably my favorite place on earth.” Later that night, they joined Rosemary’s parents for a small, celebratory dinner.
Shortly thereafter, Rosemary and her mother embarked on the planning process. “It was truly the best part,” Rosemary says. “My mom is my best friend, we talk on the phone a minimum of three times a day, and so getting to plan with her and see her so frequently for trips back home to Dallas or New York made it so special.”
The mother and daughter team worked with event planner Augusta Cole on every aspect of the wedding. “Augusta and her team are also the most amazing people,” the bride says. “They were so organized and understood our vision from the moment we first started planning.” As an interior designer, Rosemary is no stranger to color and pattern play. “The way Augusta was able to execute this mentality through her tablescapes and decor ideas is truly remarkable,” Rosemary says. “Cathy Kincaid, has designed my family’s homes for a long time, and I even had the pleasure of working for her out of college—and much of her design aesthetic was a huge inspiration for our wedding. We all wanted to evoke the feeling of being in one of Cathy’s homes.”
In the lead-up to the wedding, Cathy hosted Rosemary and Augusta at her office so they could sort through her fabric library in search of inspiration. “We honed in on Lisa Fine fabrics,” Rosemary says. “Given our relationship with Lisa, she gave us very special permission to utilize her iconic Persian Garden wallpaper for the ceiling of our tent which was really the anchor of the design and palette.”
They then also used other Lisa Fine fabrics for about 90% of the wedding decor. Augusta and her team thoughtfully mixed the patterns together with everything from the tablecloths, to the chair shrugs, to the fabric light fixtures. Floral designer Margaret Kane Ryder and her team at Kane & Co. brought color and life to the tent using floral, greenery, citrus, and styled niches to create a homey feel. “There were so many badass female powerhouses who came together to make this vision come to life,” Rosemary says.
Rosemary took a similarly thoughtful approach to her wedding fashion. “I joked that obviously getting married to the love of my life was the most important part of the wedding, but to me, my outfit choices were a close second,” the bride says. “I have always had a love and appreciation for fashion, my mom had a children’s clothing store growing up, so it started at a very early age. I would say my style is always trying to be timeless but different, I absolutely love to find unique items.”
For the rehearsal dinner at Fearing’s Restaurant on Friday night, Rosemary wanted to feel like Audrey Hepburn—but if she lived in the Renaissance era. “Patricia Voto of One Of showed me this stunning old fabric she had in her archives, and I immediately fell in love,” Rosemary says. “She has such an amazing ability to find vintage fabrics. My friend Amy joked that Patricia dove down to the Titanic to find this particular panel. We landed on a corset top and full skirt with matching shoes.”
The welcome party that followed was at the Tex-Mex Dallas staple Mi Cocina. The Color Condition, a design company out of Dallas, created and installed colorful streamers throughout the restaurant for the event. “When I saw the Oscar de la Renta pre-fall 2024 collection, I immediately fell in love with their colorful fringe dress that I knew would be perfect for the occasion,” Rosemary says. “I paired the dress with some vibrant orange Manolo flats. Some form of the 50 mm pointed-toe Manolo is my go-to—always.”
The wedding weekend took place on the first weekend in November in Rosemary’s hometown of Dallas, Texas, and the ceremony was held at Perkins Chapel at Southern Methodist University, where the bride went to college. “The service was more than I could have imagined,” Rosemary says. “Dallas is my home and happy place. The day of the ceremony was so special to me. I got to get ready in my family home, with all my lifelong friends, and it just felt so relaxing and cozy to me.”
The bride’s ceremony dress was by Oscar de la Renta. “I really have to give credit to my mom for this,” Rosemary says. “The second I put it on, she immediately knew it was the one. The fall weather in Dallas made it super easy to commit to a strapless dress, as it is still pretty warm. But I wanted to make the Oscar dress feel a little more fall and different, so I worked with their lovely seamstress to create a little jacket for the ceremony.”
While everything had fallen into place relatively easily with regards to aesthetics, the bride and groom weren’t immune to pre-wedding jitters. “I was honestly worried for months most about the ceremony,” Rosemary admits. “I was terrified of all the eyes and thought I would need therapy to get through it—but when the big day came, I was just so excited and happy.” That said, right before the first look, the bride got a big bout of butterflies. “I got super nervous in anticipation of seeing Will, and Hannah on Augusta’s team handed me a cold can of beer with a straw in it, and it was truly the best beer I have ever had.”
Will felt similarly. “I was terrified, excited, and a bit overwhelmed,” he admits. “Our videography team put a microphone in my suit coat pocket, and I’m all but positive it only picked up my heart beating through my chest. We had an amazing priest and close family friend to the Millers, Father Tony, marry us, who helped keep me calm. Most importantly, though, I was with Rosemary, who was incredible during the ceremony. With her giggling, her smile, and her beautiful eyes, she did her best to help get me through what turned out to be incredible stage fright.”
After the ceremony, big hugs and shouts of excitement were exchanged, and guests were transported to the Rosewood Mansion via a quick five-minute shuttle ride for the reception. The bride and groom were dropped off separately to walk through the tent with their parents and Augusta prior to guests’ arrival. “It was amazing to say the least—I can certainly say my family was left speechless,” Will admits. “In retrospect, it was a nice moment to take in all the hundreds of small details and the final culmination of a years’ worth of planning before the space was filled with 200 guests.”
For the reception, the bride changed into a Danielle Frankel dress with a more fitted silhouette. “I chose the Stella dress, but added a custom lace overlay,” Rosemary says. “I wanted to create some softness to the very sexy back.”
The creative direction for the after-party that followed inside the mansion was: “a disco ball metallic crazy club moment.” “We went on a family trip to France last summer, and Le Bristol hotel’s chic lounge ‘Bristol After Dark’ inspired our own ‘Spiller After Dark,’” Rosemary explains. “We gave a nod to their neon signage with our own.” There was also a light-up dance floor, illuminated cowboy hats being passed around as fun party accessories, and DJ Souljah—and a collective sugar high—kept the party going all night. “I have a bit of a candy addiction,” Rosemary jokes. “I have a drawer in my kitchen devoted to candy. When I told Augusta that a candy bar was a non-negotiable, she really went for it. Colette and her team worked so hard on ‘Rosie’s Candy Drawer,’ and it was a huge hit at the after-party. Colette even surprised my mom and her friends with candy queen aprons, and it was the most thoughtful moment. My mom did not take off her apron for the rest of the night.”
Meanwhile, for the final look of the evening, the bride wanted to feel like she could be a cast member in Saturday Night Fever. To achieve this, she worked with Patricia Voto of One Of. “I didn’t want to give much direction, as Patricia is a true artist,” Rosemary says. “I think the best results come when you let her do her thing.” The final piece was more than I could have ever imagined.” Patricia used a vintage Miu Miu fabric as the base, and then added tons of colorful crystals to the bodice. A beaded fringe was added as well, which created a real impact on the dance floor. The bride’s friend Amy surprised her with custom Miron Crosby boots about a week before the wedding, and they complemented the look perfectly. “I was feeling myself in the boots and set,” Rosemary says. “I truly could not be stopped on the dance floor.”
