It is a functional and discreet detail that serves a specific purpose in formal or semi-formal attire. Here are the key features and information about the Hackett London Back Collar Stud: Functionality: The back collar stud is used to fasten the back of a dress shirt's collar. It is designed to keep the collar in place and maintain a neat and tidy appearance, especially when wearing a bow tie or cravat. Materials: The stud is typically made from high-quality materials, such as metal (often brass or stainless steel), to ensure durability and longevity. Design: The design of the back collar stud is simple and functional. It consists of a small, cylindrical or disc-shaped piece with a threaded post on one end and a screw-on cap on the other. The cap is often engraved or embossed with the Hackett London logo or branding. Versatility: Back collar studs are primarily used with wingtip or wing collar shirts, which are commonly worn for formal events, such as weddings or black-tie affairs. They help maintain the collar's shape and prevent it from folding down. Secure Fit: To use the back collar stud, simply insert the threaded post through the buttonhole on the back of the shirt's collar and screw on the cap until it is snugly secured. This ensures that the collar stays in place throughout the event. Subtle Detail: While primarily functional, the back collar stud can also be a subtle and elegant detail that adds to the overall aesthetics of a formal outfit. It contributes to a polished and well-put-together appearance. Hackett London Branding: Look for discreet Hackett London branding, which may be present on the stud's cap or packaging, showcasing the authenticity and exclusivity of the brand.
