Woocommerce 2.0.3 update changed all of my styles

Hello.
I have a WordPress eCommerce site using the a child theme of Blance and I recently did the woocommerce update. When I was styling the site I ran into a post that suggested turning off the woocommerce styles and copying the woocommerce.css into my child theme css and altering it there which is what I did. It was very helpful advice, but Since I updated to Woocommerce 2.0.3 my style.css file with the correct styles is being overridden by the new woocommerce.css and I would like to turn off the woocommerce styles again and cant find that option any more. Is there any way I can override the woocommerce.css with my style.css file again? Any help would be much appreciated. Thank you in advance!
