Styling Currency Flags (wSelect)?

Hi, I’m trying to help a friend out with his woocommerce website and I can’t figure out how to style the currency flags (he’s purchased the add-on).

There’ seems to be an inline style on it, and an embedded style to define it’s width:

<select class="woocommerce-currency-switcher wSelect-el" onchange="woocs_redirect(this.value); void(0);" data-flag-position="right" data-width="100px" style="width: 100px;" name="woocommerce-currency-switcher">

and:

<style type="text/css">
.woocommerce-currency-switcher-form .wSelect, .woocommerce-currency-switcher-form .wSelect-options-holder {
width: 100px !important;
}
</style>
