[Plugin: Woocommerce] Customizing Woocommerce CSS

Okay so when i click on “Enable CSS Styles” in the General Woocommerce Settings, but it’s all messed up, the only thing i like about it is it moves the gallery to the left and puts the essentials like the add to cart button the the right. Like this:

I want to keep my theme’s styles/sizes/colors, but i want the placement like it is shown in the screenshot (link here).

How do i go about making this happen?
