This is a shirt blouse from BACCA. I purchased it a few years ago at the B-Edition in Shinjuku. It's made of silk, but has the feel of a thin knit, so it can be worn year-round, in spring and autumn, as well as indoors with strong air conditioning in the summer, or as an inner layer in the winter. * The original button is missing, so the third button from the top has been replaced with a commercially available one. There is some slight pilling in some areas, so please refrain from purchasing if you are concerned. The item is still in good condition, but I am decluttering as I have too many similar clothes. Sheer black long-sleeved shirt with two front pockets. - Brand: BACCA - Color: Black - Size: 36 - Style: Long-sleeved shirt - Features: Sheer material - Pockets: Two front pockets Thank you for looking.
