Elise, thank you!
But if I do this, all underline from all links will disappear. The only underline I want to remove is (a) underline from the arrows (b) second underline from the product name.

Here is my overall CSS for links, what should I change?

/*Change default dressing of links*/
a:not(.tabs wc-tabs) {
color: #C41E3A;
text-decoration: underline;
}
a:hover {
color: red;
}
.wpb_wrapper a {
color: #C41E3A;
text-decoration: underline;
}
.wpb_wrapper a:hover {
color: red;
}
.woocommerce-product-attributes-item__value a {
color: #C41E3A;
text-decoration: underline;
}
.woocommerce-product-attributes-item__value a:hover {
color: red;
}
.meta-post-categories a {
color: white;
text-decoration: none;
}
.meta-post-categories a:hover {
color: white;
text-decoration: underline;
}
.read-more-section a {
text-decoration: none;
}

Thanks for your help!
