Cufflinks are used on special cufflinks shirts instead of cufflinks. They are about the same size as ordinary buttons, but because of the exquisite material and shape, more styles and customization requirements, very good. The role of decoration, inadvertently, let men's original monotonous dresses and suits have unlimited scenery.
The female faces on both sides of the cuffs of the French shirt are in contact with each other, so that it is not a ring, but has a "6" shape effect. The use of the cufflinks is to put the needle connecting the "button" portion of the cufflink from the cuff of the back of the hand, and then pass it out from the cuff on the side of the palm and fix it.
Of course, if you use a cufflink's close relative "sleeve chain", which is called a "double-headed button", then it doesn't matter, both sides are also "buttons", and your hands can be in any state. Show the "button".
The cufflinks only match the French shirt, unless you have to make a hole in the ordinary shirt.
