Vintage tartan pants

Feeling very Canadian? These red tartan pants (Maple Tartan) are made in Canada, complete with a Union label! They are 100% wool and have a side zipper. They are marked as size 12 but have been taken in at some point. So might fit like an 8 or a 10? Measurements (approx.) : 13 in rise, 13 in waist and 26 in inseam.
