I recently purchased this item new on Mercari, and it's practically new, only tried on. It's light and airy, and not very see-through, so I think it would be easy to wear in the office during any season except for the peak of summer. There aren't any S-size versions of this same item currently listed, so I recommend it! *Please refer to the 8th photo for the size.
