These are leggings, spats, and tights. Size is 150. I used to have my son wear them. I've erased the name written on the tag with a marker. There are no noticeable stains, but please understand that these are used items. I think they'll be warm when worn under pants. The waist is elastic. Length: Approximately 75.5cm I will compress them for shipping. #leggings150 #spats150 #tights150 #heattech150
