BOZZOLO black leggings, made with 92% nylon and 8% spandex for a comfortable fit. They are still wearable, but there is some pilling overall, mainly around the seat. It might not be very noticeable depending on the angle. They are perfectly fine to wear under costumes for dance or theater. How about for yoga, Pilates, etc.? Purchased in the US, but the sizing is quite small. I think it's equivalent to a Japanese S. - Brand: BOZZOLO - Size: S/M - Material: 92% nylon, 8% spandex - Color: Black Thank you for looking.
