A halter neck dress does something very specific for your shoulders and your back that basically no other neckline achieves. The straps that tie or fasten behind the neck create a wide open back and a frame for the décolletage that’s genuinely stunning. They work best with a good self tan or a holiday glow but honestly they look great either way. These are the halter neck dresses we’ve been reaching for, from casual summer versions to more dressy options for evenings out.
