These are wide-leg pants made of 100% cotton. The thin fabric makes them perfect for hot summers. They are free size, but they are made quite large. I usually wear a size M for pants, but since they have an elastic waistband, they didn't fall down! I've worn them about twice. I am 163cm tall, and they are ankle length on me. The color in the third image is closest to the actual color. They don't have a lining, but I don't think they are see-through. Available for immediate purchase. Thank you for looking.
