I received an invitation to a wedding titled Burgers and Vows. The guests are asked to wear white.
^^Are you going to go? (oh please say yes!)
Sounds fun. Don’t spill mustard on that white outfit! 
Agreed and agreed. Not tacky, just quirky.
Serving burgers at a wedding = fun.
Imposing an all-white dress code on guests = PITA (if not outright tacky).
You MUST go so you can report back to all of us. [-O<
