Rehearsal dinners are a moment to bond with both your family and your significant other’s family and friends. If they have not met before (like our families did) then it could turn a bit awkward. So to add to that stress you have to plan for a place, the menu, whether you will have a fixed menu or each person gets to order what they want.
The one thing I can tell you is that you should be comfortable, whatever you choose to wear that night, while you want to feel cute and your best self, remember that the night will be hectic and you are there to enjoy it, not to be bothered by over complicated outfits. I wanted to be super comfy so I got this SammyDress white lace dress and Rose Wholesale short sandals that kept me going all night.
