Bachelorette game - Everyone attending should bring a pair of (BRAND NEW in the bride's size) panties that ‘represents’ them or would somehow remind the bride of them. Then, you lay out all the panties and the bride must guess which panties belong to each guest. If she’s wrong, she has to take a drink. If she’s right, the guest drinks. The bride gets to keep all the underwear as a souvenir. Hahaha cute
Wedding guests write notes and slip them in whatever year bottle they want. Open it on your anniversary of that year.--this would be especially special for the later years where maybe some of the people who put something in those bottles passed away.
