This is a top purchased from a discount oriental clothing manufacturer so I would not trust their size labeling. I go by the measurements alone. It is a yellow rayon-type material over a white rayon-type material. The problem is there is no label that says what the material is nor what the garment care is. t is in brand new condition, never worn. There are no stains, no rips or tears. It comes from a smoke-free home but we do have dogs. Please note: Due to differences in how color is displayed, the color in the photos may look different than the item appears in person. Size 5XL?? Bust: 52 inches Length: 25.5 inches Shoulder to shoulder: 16 inches Check out the pics and email me with any questions you have. Thanks for looking!
