This dress is an old one from Mango. I like the dress as it goes with many styles: you could go with leggings, pumps, sandals or even sneakers. Wear it over a jeans or with a jeans jacket etc. Also you could play with belts to create a glamorous style: golden belt, trendy: studded belt or a clean look: brown belt- as the dress come with.
