This is a thin, lightweight blouse. I've worn it once. It has a white lining except for the sleeves. The sleeves are slightly sheer. It's a long-sleeved blouse, but it doesn't feel heavy, making it perfect for the coming seasons. Great for sun protection and air conditioning. Color: White系 (White-based) Sheerness: Sheer Season: Spring/Summer Stains, tears, odors, etc.: None Material: Polyester (synthetic fiber)
