DESIGN- This is a form fitting tank top that has a cool criss cross shape in the back. The shape reminds me of an ocean shell, so that's why I called it 'Mermaid Top'. This top does not have a built-in bra. If comfortable, you can wear it with no bra, or you can use a sports bra or bandeau top underneath. A racerback sports bra looks and works well underneath for athletic practices. The length goes below waist line, and can be dressed up with a belt.
