The double collar shirt is like the name would suggest, a shirt with two collars – or at least the appearance of two collars (like shown on the left). The double collar shines a hidden collar underneath the original, bringing you the design that will be primarily noticed in a shirt. Making you look attractive and different from your environment, it can be customisable to your choice and design. A single collar shirt (like shown below) is more formally worn and brings upon simplicity to the shirt. However, to make it look less simple you can add your own design, number of buttons and many more options to make it look vogue or keep it simple with a nice and classy collar.
