When Nell Diamond founded Hill House Home in 2016, her focus was on home goods—bedding, pillows, and sleepwear. But in 2019, one product changed everything: the Nap Dress. A modern take on vintage smocked designs, it was effortless, comfortable, and elegant enough for any occasion.
At first, the dress was just another addition to the brand’s lineup. But when the Covid-19 pandemic hit, it became a symbol of both comfort and versatility. People stuck at home wanted clothing that was stylish yet easy to wear, and the Nap Dress fit the bill perfectly. As social media buzz grew, demand soared, turning a single product into a cultural movement.
The turning point came in 2020 when Hill House Home saw a massive surge in sales. "I could see the numbers growing, but the moment it really hit me was when I looked out my window in New York City and saw a stranger wearing our dress," Diamond recalls.
By 2021, the brand had sold over a million Nap Dresses, expanded into new categories like outerwear and swimwear, and opened five retail locations across the U.S., including in New York and Charleston. Today, Hill House is valued at approximately $150 million and continues to grow beyond expectations.
So what makes the Nap Dress so special? According to Diamond, it’s all about the fit and versatility. The signature smocking stretches to accommodate different body shapes and sizes, making it a favorite for women at all stages of life—including pregnancy.
“We didn’t invent smocking,” she explains, “but we perfected it in a way that feels modern and timeless at the same time. Our customers love how it moves with them throughout the day.”
Of course, rapid success comes with its own set of challenges. Hill House Home had to navigate global supply chain disruptions, scale production, and manage surging demand. "There were times when shipping delays threw off entire product drops," Diamond says. "But we were transparent with our customers, and they appreciated the honesty."
That transparency, she believes, is one of the reasons Hill House has built such a loyal following. Instead of feeling like just another brand, customers feel connected to the company’s journey.
While the Nap Dress remains at the heart of the brand, Hill House Home is expanding into new categories and in-store experiences. The company recently launched a swimwear collection and introduced Nells, a candy and coffee station inside its Charleston store, blending British heritage with American nostalgia.
Despite the ever-changing fashion landscape, Diamond remains focused on one thing: serving her core customer. "Trends come and go, but our goal is to create pieces that make people feel good—year after year."
For those looking to build their own business, Diamond’s advice is simple: stay focused and tune out the noise. "I used to compare our brand to others, but that never helped. The biggest lesson I’ve learned is to put blinders on and trust our own vision."
From a small bedding brand to a $150 million fashion empire, Hill House Home’s success story proves that sometimes, all it takes is one great product—and the right moment—to change everything.
