As far as I know, it's not really possible to make a border around an element with a clip-path. This method uses inside and outside elements. Source: https://codepen.io/bennettfeely/pen/azJWWX/

.outside {
  position: relative;
    width: 70vmin;
    height: 70vmin;
    background: red;
    -webkit-clip-path: polygon(50% 0%, 83% 12%, 100% 43%, 94% 78%, 68% 100%, 32% 100%, 6% 78%, 0% 43%, 17% 12%);
clip-path: polygon(50% 0%, 83% 12%, 100% 43%, 94% 78%, 68% 100%, 32% 100%, 6% 78%, 0% 43%, 17% 12%);
}

.inside {
  position: absolute;
  top: 5px;
  left: 5px;
  right: 5px;
  bottom: 5px;
  background: red;
  -webkit-clip-path: polygon(50% 0%, 83% 12%, 100% 43%, 94% 78%, 68% 100%, 32% 100%, 6% 78%, 0% 43%, 17% 12%);
  clip-path: polygon(50% 0%, 83% 12%, 100% 43%, 94% 78%, 68% 100%, 32% 100%, 6% 78%, 0% 43%, 17% 12%);
}

.inside:hover {
  background: white;
  transition: all .2s;
}

.outside:hover {
  background: green;
  transition: all .2s;
}
