Size 2 or size 24/25 waist. True waist measures at 26 inches but has zero stretch and does not fit me who usually wears size 26. Wonderful vintage short, but zero stretch in the denim. No stains or issues. Worn in as is vintage denim You can see me in the photos for reference (I can no longer button the shorts hehe). But I typically wear 25/26 in denim depending on the brand, cut and level of stretch.
