.baseclass {
    position: relative;
    width: 116px;
    height: 142px;
    margin: 6px 0px 0px 6px;
    > img {
        width: 114px;
        height: 114px;
    }
    &__label {
        padding-left: 5px;
        line-height: 22px;
    }
}

.baseclass--modifier {
    @extend .baseclass;
    > img {
        opacity: 0.5;
    }
    &__label {
        color: black;
    }
}

sass output:

.baseclass, .baseclass--modifier {
  position: relative;
  width: 116px;

  margin: 6px 0px 0px 6px; }
  .baseclass > img, .baseclass--modifier > img {
    width: 114px;
    height: 114px; }
  .baseclass__label {

    line-height: 22px; }

.baseclass--modifier > img {
  opacity: 0.5; }
.baseclass--modifier__label {
  color: black; }
