This "Resto-Vival" pattern dates to about 1937 for nautical inspired slacks that lace up with eyelets at the inside center front waist and are held up at the outside with large buttons and a belt that passes through a bound buttonhole. The slacks can be made in two different lengths.
This pattern includes cutting charts for modern 45" and 60" fabric widths. Note that vintage instructions may be difficult for the modern sewer to comprehend.
