Swallow collar, also known as wing collar, is simply the collar above the vertical collar. It is a small pointed collar that folds outward and looks like the wings of a swallow. For those men who wear evening dresses, their shirts are usually tuxedos with ties. Nowadays, tuxedo is no longer a gorgeous dress. If you choose it properly, it can also appear as a beautiful collar or show that you have a very good brooch.
