Stepped up essentials. Bandeau dresses - or strapless dresses - are a true closet staple, perfect for almost any occasion, from wedding guest days to date nights. White strapless dresses and black strapless dresses are the ultimate versatile closet piece, as they can be styled in a huge range of ways. Pair tube dresses with chunky boots and a blazer for office days, or with statement heels for nights out and parties. You can even layer a crop top over them to create a top and skirt illusion. Strapless mini dresses will see you seamlessly from day to night, and you’ll wonder what you ever did before you had them in your closet rotation.
