• A "button cover" is not the same as "studs".  A button cover is a larger piece of jewelry that can fasten over the top button of a shirt. 

Formal style dictates that seeing your buttons seems downright unseemly. And that sharp tuxedo you're sporting calls for above standard button covers to do the job. Go the luxurious route with button covers set in lustrous black onyx lined with sparkling rhinestones and shining gold trim. An over-the-top look for an over-the-top evening.
