Jay Day Dress Co. is one of the last remaining family-owned luxury fashion houses in America. Founded in 1932 by visionary garment tycoon Jack Davis, the brand has been thoughtfully revived nearly a century later by his great-granddaughter, Julia James Davis, also the founder of The War on Beauty.

Under Julia’s leadership, Jay Day is reasserting its place in the fashion world by honoring its heritage while boldly confronting the industry's future. At the heart of this revival is the groundbreaking Promise Dress by Jay Day—a single dress with over 20 distinct styling options. More than a dress, it’s a movement—an elegant, intelligent response to the fashion industry’s crisis of overproduction and waste. Designed with versatility and longevity in mind, the Promise Dress challenges the relentless pursuit of “new,” promoting a more sustainable and mindful way of dressing.

As Jay Day nears its 100th anniversary, Julia has preserved the brand’s founding ethos: delivering timeless, ladylike elegance through refined, high-level design. The house’s carefully curated jewelry line reflects this same commitment to heirloom quality pieces and luxury, embodying the enduring quality expected of a century-old legacy.
