Hello I would like to put a condition on the name of the option if the object sku.attributes is empty the name is same product otherwise it displays the color and size

skusListProduct = [{attributes:{size:'m', color: 'black'}}] // ex array
            <select
              v-model="skuList"
              @change="productChoice"
            >
              <option
                v-for="sku in skusListProduct"
                :key="sku.id"
                :value="sku.id"
              >
                <span v-if="sku.attributes && sku.attributes.length > 0">
                  {{ sku.attributes.color }} {{ sku.attributes.size }}
                </span>
                <span v-else>
                  same product
                </span>
              </option>
            </select>

I'm do that but is doesn't work
