black textured "shibori" / technical pleated top by Issey Miyake me slightly sheer as indicated by the hand pic, but since it's black it's not noticeably sheer (I didn't need to wear and undershirt/ layer with it) free size & stretchy material - i am a size small / 34 inch bust and it fits comfortably with room to spare / stretch 100% polyester - typical of the designer send offers
