Going to have some stretch to them but I don't know how much. Measuring 38" on a flat lay, I'm guessing they're going to fit 39 or 40 ish. Please review photos for measurements. Please see photo's for condition and measurements. Due to the nature of pre-owned clothing, it's possible the measurements may differ from the size tag and/or clothing you already own. Please compare the measurements to your current wardrobe to ensure a comfortable fit! We offer a combined shipping discount!
