The yellow-and-brown floral-print dress is modest and feminine. Pretty. It has three pleats down the front and long sleeves. It wraps at the waist.

It isn’t a groundbreaking design, but it is a dignified one. Most important, it was sewn by Rosa Parks, whose refusal to vacate her seat on a Montgomery, Ala., bus in 1955 gave rise to the civil rights movement.

“She was a seamstress for a department store,” says Spencer Crew, guest curator at the National Museum of African American History and Culture. “Most often [Parks was] altering clothes that would belong to white Southerners.” In taking a stand against segregation, Parks was putting her livelihood in jeopardy. Parks wasn’t wearing this dress that day, says Crew, former director of the National Museum of American History. That garment is lost to history. But this, he says, is “as close as we can get to that moment in time.”

The dress survived because of Lois Alexander-Lane, a black woman who loved fashion, not just for its beauty, but also for what it meant to African Americans: dignity, entre­pre­neur­ship and self-determination.

Born in Little Rock in 1916, Lane wanted to be a designer, but the times put insurmountable hurdles in her way. She moved to Washington and found a job with the federal government. Eventually, she relocated to New York, but her love of fashion never faded. She was also active in the civil rights movement. “My mother actually knew Rosa Parks and considered her a friend,” says Lane’s daughter, Joyce Bailey.

In 1975, Lane organized “A Bicentennial of Fashion,” celebrating the creativity of African Americans. Because Lane cared about provenance — not simply aesthetics — she asked Parks whether she could display the little floral dress, which Parks had reportedly made for her mother.

“Mrs. Parks was actually carrying the dress in a carryall when she was arrested on the bus,” Bailey says.

In 1976, Parks gave the dress to Lane’s more ambitious project: The Black Fashion Museum. And after Lane died in 2007, Bailey donated her collection of more than 2,000 garments and accessories to the African American Museum.

“My mother always wanted to make a contribution to the race,” Bailey said at the time. “You don’t hear that much anymore.”
