Purchased in the US, so it's labeled as a size S, but I believe it's equivalent to a Japanese size M. Please check the images for the mesh detail on the calves. Please note that I may have missed something during my amateur inspection. Packaging will be simple, using materials I have at home. It may be shipped in a compression bag, so please refrain from purchasing if you are concerned about wrinkles. Returns are not accepted. I do not have any pets, and I do not smoke. Please consider this item, understanding that it is used and has been stored at home. ^ ^ #nike #ナイキ (Nike) #レディース (Ladies/Women's) #レギンス (Leggings) #ヨガ (Yoga)
