ok to be totally honest, this tank top isn't exactly what I thought it was when I ordered it but it is still super cute. it is a black silk tank top with lace detail on the straps and around the chest. I personally paired it with this cardigan and I think it would pair great with any cardigan or even a blazer if you wanted to dress it up. I would say it runs true to size. In the pictures I am wearing the medium, but I need the large because of my chest.
