same design as the theme in “WooCommerce Multi Currency”

Hi, I’ve been reading and I couldn’t find any info on this. As you see in the image of the attached, I placed the shortcode that you provided and I don’t like anything as it looks with the design that I have in the website.

So, I want to know how can I make the currency drop-menu with your plugin, using the same design of the theme? (look how it looks when I do over in “SHOP”)

Many thanks
