I've worn it a few times, but there are no stains. As shown in the photos, the waist is elastic and has a drawstring. I think it can also be used as a maternity dress. Also, the skirt part below the waist has a lining, so it's not see-through. The sleeves are three-quarter length and have buttons, so I think it would be cute to roll them up. When I, who am 159cm tall, wear it, the length covers my knees. The color is not a vivid blue, so I think it's easy to wear regardless of age. Instant purchase is OK. I'm looking forward to your comments.
