Vintage 60s 70s flare bell bottom sailor pants

Incredible pair of true vintage ultra wide flare pants from the brand Chequers. Similar to modern day Jesse Kamm sailor pants. No size or fabric tag present but there are extensive measurements in the photos and it feels like polyester or poly blend. Good vintage condition with some minor flaws - loose stitching at the front pockets, some light pilling, a few light smudges near the lower legs. No holes, smells, or other major flaws.
