Thank you for viewing. There's a comfortable amount of elastic under the bust, so it doesn't feel constricting. It's thin and somewhat see-through, but the parts other than the arms have a lining to prevent transparency. ※ See the last image. I'm selling this because I recently bought a similar item. ● Size Shoulder width: 40cm Sleeve length: 58cm Length: 76cm ※ Please note that there may be slight variations due to amateur measurements. ● Material 100% Polyester ● Condition Worn once, but there are no stains or snags. Please understand that this is a used item before purchasing.
