The crew neckline has a rounded style that’s cut close to the neck, usually sitting right by the collarbones. It’s among the more conservative neckline options and can be seen with any length of sleeves or even sleeveless. Dresses with crew necklines are particularly appropriate for professional occasions and can be styled with a statement necklace that sits just as close to the neck. This style looks especially good if you have a long neck to accentuate.
