1979 DuPont Subtract Firm Control Briefs

1979 Dupont Subtract Firm Control Briefs, New. Firm Control for Weight Losers. Size 40. The waist is about 15.5" wide. There is a slight yellowing dued to age, not use. They still have the tag attached.

This is a remarkable time capsule of late 1970s foundation wear: a pair of DuPont Subtract "Firm Control for Weight Losers" briefs, preserved in new-old-stock condition. Designed during an era focused on the "streamlined" silhouette, these briefs feature a high-waisted fit and a reinforced front panel adorned with a subtle, tonal floral knit pattern. The engineering of the garment relies on the signature DuPont fiber technology of the time, promising a supportive yet flexible fit that was marketed specifically to those transitioning through fitness or weight loss journeys.

Finding intimate apparel from this period with the original factory tags still attached is exceptionally rare. The paper hangtag features the classic bold typography and graphic design of 1979, serving as a fantastic piece of fashion ephemera in its own right. While there is a very faint yellowing to the white fabric—a natural and honest characteristic of aging elastics and fibers over nearly five decades—the material remains strong and the garment has never been worn. This piece is a must-have for collectors of vintage lingerie or fashion historians interested in the evolution of shapewear and the marketing of "control" garments in the post-disco era. It would be a fascinating addition to a boudoir display or a study of mid-century textile innovation.
