Viral Zara white satin backless top

Got this from the store and tried it on at home but the size is small for me. It is new and tag is still on. You can tie the back and the look is honestly very nice. I am just selling cause the size didn't fit and the return window passed. Note: There is foundation stain near the neck (visible on the last pic). It was like this when I bought it -- honestly it is not very realisable I didnt't even notice in the store.
