Adult women's size, usually a size S, so I used a children's size 150 as pajama bottoms once, but since they are originally spats, they were too tight. They are thin fleece-lined. Also suitable for pajamas and loungewear. Image 5 is the inside out. The size 150 and material information are printed on the inside right of the rear, making it easy to tell the front and back. Heather gray, image 4 is the closest color. Please refrain from cancellations or complaints due to color differences from the actual product, or the presence of dust, even though we try our best to remove them. Black is also available. If you want to buy two, please comment. Please comment before purchasing as it is also listed on other sites.
