In 1917, just before the U.S. entered WWI, The H.D. Lee Mercantile Company was the first workwear manufacturer in the U.S. to offer a one-piece coverall to women in the factory workplace. Think Rosie the Riveter and her sweet jumpsuit. That was us. Now, over 100 years later, this trendy one-piece was re-created purely as a fashion piece but still rocks the lady boss look with our authentic Lee details, which include 100% lightweight cotton denim fabric, a full-body metal zipper, and an iconic Union-Alls™ woven label.
