Show Additional Information in Product Short Description

My website using WP 3.8.2 and it’s used to sell sport products.
I added some attributes to each soccer shoes and now I’d like to show SIZES, COLORS.. in the Product Short Description area.
It’s easier for customers to see it then they have to scroll down, click to Addition Information tab.

After adding these codes

<div class="post-content" itemprop="description">
            <?php echo apply_filters( 'woocommerce_product_additional_information', $post->post_excerpt ) ?>
            <?php echo apply_filters( 'woocommerce_short_description', $post->post_excerpt )?>
</div>

to

plugins\woocommerce\templates\single-product\short-description.php

I have this change (pic2) instead of the top of Product Short Description.
