You may find cufflinks a little fiddly to put on when you first start using them. However, over time you’ll begin to find the process easier. Precisely how you put on your cufflinks will depend on their style. For standard bullet back or T-bar cufflinks, you must first move the small horizontal bar into a vertical position.
Then, slide the end of the cufflink through your outside and inside cufflink holes. The interiors of each side of the cuff should be touching. Now, return the bar to its original position to secure your cuff and cufflink. Other cufflink styles, such as those with a fixed back, do not feature a movable bar. As such, they need only be pushed through the holes to stay in place.
