This looks pretty close, I am also trying to make the concave curve at the top but it is not working.

I'm not sure if my answer provides anything that kougiland's doesn't, but I did it so I figured I might as well post it.

It looks like this.

enter image description here

Here's the codepen.

The HTML looks like this.

<div class="tab-bar">
  <div class="tab">&utrif;</div>
  <div class="tab">&utrif;</div>
  <div class="tab">&utrif;</div>
</div>

The CSS looks like this.

body {
  background-color: #eee;
}

.tab-bar {
  overflow: hidden;
  text-align: center;
}

.tab {
  margin: 0 1.55rem;
  color: #999;
  display: inline-block;
  position: relative;
  top: 0.1rem;
  width: 9rem;
  font-size: 3rem;
  line-height: 3rem;
  background-color: #666;
  transform: perspective(4rem) rotateX(-20deg);
  border-radius: 0 0 1rem 1rem;
}

.tab::before,
.tab::after {
  content: " ";
  display: block;
  position: absolute;
  width: 1rem;
  height: 1rem;
  top: -1rem;
  border-color: #666;
  border-style: solid;
}

.tab::before {
  left: -1rem;
  border-radius: 0 2rem 0 0;
  border-width: 1rem 1rem 0 0;
}

.tab::after {
  right: -1rem;
  border-radius: 2rem 0 0 0;
  border-width: 1rem 0 0 1rem;
}

Very nice, +1 for a modern approach. Personally I'd go with this, however since it doesn't work on IE9 and below, it may or may not meet the OP's needs.
