Vintage off white full length pull on pants liner with lace trim, size S/M. These are in excellent condition, but there’s a slight discoloration as seen in pics. (I could only see it in the sunlight). Size tag is blank, so estimated S/M based on measurements & other items from the original owner. Measurements approximate. Waist: 13” Rise: 12.5” Inseam: 24”
