Thank you for viewing. It has an elastic waistband and the hem can be tightened. The fabric is a thin, slightly rustling material. I purchased it two years ago and wore it a few times, but I am selling it due to a major decluttering associated with moving. It is a used item stored at home. Please consider this, understanding that it is a used item. Color: Blue系 (Blue-based) Stains, tears, odors, etc.: None
