I am hosting an engagement party for my best friend who is getting married next summer. She thought it would be fun to have a "stock the bar" theme for the occasion. However, as this party is really informal (mostly close friends invited, serving appetizer-y type food at the couple's home), we wanted to make it clear that gifts are in no way expected. I'm not sure how to politely phrase "Don't feel obligated to bring a gift, but if you want to, an item to stock the couples' bar would be greatly appreciated."
Does anyone have any ideas? I've never attended an engagement party, let alone hosted one, and I'm a little bit lost in the whole process.
Thanks for any suggestions!
