This is a cache-coeur style top. It's made of thin fabric. In the third photo, there's fabric at the chest, so you can wear it on its own. The eighth photo shows the chest area, inside view. In the fifth photo, you can see that you can adjust the fit, making it tighter or looser. Total length: 66cm Width: 41cm (slight variations may occur) There was no size tag, so I've listed it as M size, but I, who usually wear M or L size (mostly L size), could wear it. The tag in the third photo is a cleaning tag. Please understand that this is a used item and has been stored at home, as it has been worn several times.
