Hi [friend's name],

I hope this message finds you well. I'm writing to invite you to a [holiday/event] celebration that I'm hosting on [date] at my place. I would love for you to join me and [other guests, if applicable] for a fun-filled evening of [activity or theme].

Please let me know if you can make it, and if there's anything you'd like to bring or contribute to the festivities. It wouldn't be the same without you, and I'm really looking forward to spending some quality time together.

Best,

[Your name]
