Larger Font Size for Product Categories

Site URL: https://www.kelseyrodriguez.com/shop

Hi everyone! 

I'm trying to make the font size on my shop page a bit bigger than they are right now, as they're pretty small when using my default settings. As you can see in the image, the font size of the categories below "shop" is pretty small.  I'd like it to be a similar size, and am just struggling with how to target it with CSS. 

The link to my site is: https://www.kelseyrodriguez.com/shop

Use password 'yellow' all lowercase.

Any help would be super appreciated, thanks!

    font-size: 53px;
}
