This was how I asked the most important women in my life to be my bridesmaids! Custom labels with a P-J Peacock logo for the theme of our wedding.
I made the lables and put them on their favorite type of wine (or vodka), I even got sparkling white grape juice for my junior bridesmaid! On the back I wrote individual poems for them asking them to be my bridesmaid and reply via social media using our wedding hashtag.
You can have them save the bottles or bring them to a specific wedding function, open them together and make sure to give the bottles back for them to take home!
