Delle Donne was a New York-based millinery house active during the mid-20th century, particularly known for its production in the 1950s. The brand was part of the thriving New York City millinery industry centered in the Garment District. While based in New York, their designs were sold in high-end millinery shops across the country, including retailers like Isabel Pickerell Millinery in Los Angeles. Their hats often featured feminine, structured silhouettes common to the era, such as small "perch" hats with feathers or wide-brimmed straw hats trimmed with velvet bands and ostrich feathers.
