Vintage Military Camo Cargo Pants Size Medium

Reposhing this item I purchased from @zachschade. Loved it, but......... This item is smaller than it says on the tag (M) and won't fit me. I wear 34" waist and this "up to 35" was tight on me. It says 100% cotton so I'm assuming it was washed in hot water and dried already to shrink it but don't know for sure since I didn't get any response from the seller. I'm changing the M to S
