Subject: Let's Go Shopping!

Hey [Friend's Name],

Hope you're doing well! I was thinking of heading to the shopping centre this weekend and wanted to see if you'd like to join me. It's been a while since we've hung out and I thought it would be fun to do some browsing and maybe even treat ourselves to a little shopping spree.

Let me know if you're free and we can plan a time to meet up. I'm excited to catch up and spend some quality time together.

Looking forward to your response!

Take care,
[Your Name]
