The tradition of a groom wearing a boutonnière hasn’t changed much since it’s medevil beginnings. Back then knights in shining armor (literally) wore a flower to match the clothing of the woman he admired. Today, it’s pretty much the same, only your knight is usually in a tux and it is completely acceptable to forgo flowers. If you are looking for a traditional floral boutonniere or something with a bit of a modern twist for your groom, whatever you decide, it will be exactly perfect.
