Groom and groomsmen inspiration

So I've been looking up ideas for David and his best man and the groomsmen. Since my dress is gun metal grey, David wants to wear a silver tie and vest. I found one, but it's not exactly what I want. So while looking for inspirations I came across this one...

This one looks like a darker silver and I like the pattern. The flowers on the right just happened to be part of the pic, but mine would be red...
I also like the red and silver one above (top row, middle), and the red paisley one beside that one.
