Debut Theme Checkout Sender and Recipient Info

Hi,

I am using Shopify Debut Theme. As I am in the gifting business, i would require to get both the names, contact and address for both sender and recipient.

At the checkout page of the Debut Theme, there is only information collected for 1 party. How can I add more fields to gather information for the 2nd party? (in this case the recipient?)

Thank you in advance for your advice. my website is www.laurenglacia.com

With regards

Ignatius
