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

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:
ENQUIRE NOW

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!
