These are collaboration pants with Instagrammer Saya. They can be worn year-round! The fabric is soft and comfortable, and slightly stretchy, making them easy to move in. The flared hem makes them look beautiful when worn. These pants can be worn casually or in a more polished style. I am also selling the same series in brown. I've worn them a few times, but I'm selling them. Please consider this item, understanding that it is a used item.
