These little cigars are simply tacky. You don't need studs anyway. Just button the shirt buttons. I wondered why this shirt had buttons if you were suppose to wear studs. Either buttons or studs are acceptable.
Studs are a little more formal than buttons.
If you don't use studs, all you need is a pair of plain gold cufflinks. Here, you can use the ones I'm wearing to get the effect. Looks like the shirt fits. I would recommend the cummerbund. The vest is too formal for the Tonys, and if you wear it you need the studs.
