There are several, a few follow here: Crewneck This type of collar is considered a 'collar-less' look on a shirt, which is characterized by a cuff-like, rounded finish. Johnny Although some variation exists, typically a traditional fashion collar sewn into a V-neck silhouette. Shawl A turned-over, continuous collar that drapes down slightly in the front. V-neck Collar that is cut in the shape of the letter 'V'. Turtleneck A tubular (some have seams in the back), close-fitting collar that covers the neck. Because of its length, it is worn either turned over or scrunched down on the neck. Mock-turtle Like a turtleneck, but this collar sits lower on the neck, does not fit as close and is not designed to be turned down.
