Replacing ATC button with email link - How to output Variant text?

[Justinvz777]

HI, I am replacing my ATC button with an "Enquire Now" button, that will email the store admin the details of the product. How Can I add the selected Variants text to the email subject? 

This is my code for the button:
<a href="mailto:{{ shop.email }}?Subject=Website Product Enquiry - {{ product.title }} - ">ENQUIRE NOW</a>

Ideally Id like it so say "Product title - King Single - Oyste with Navy Border Qty:1 " using the details from the screenshot below. Is this possible?

Thanks in Advance!
