I recently purchased this, but I've decided to wear a different color, so I'm putting this up for sale. This is a different fabric from the pants I'm currently selling. The tag has been removed, but it's new. It's a size for adults. Please refer to the size chart. It's a bright navy blue, close to the last color shown. The material is stretchy and easy to move in. The sewing thread is gentle on the skin. The cotton is organic cotton. The seller is 155cm tall. I usually wear S or M size. However, I've recently been liking the 140-150cm size of this series and wear them often.
