I really want to know if there's any special invitation wording I should use to indicate that my reception will be very laid back but the ceremony is traditional. My ceremony will be a Catholic Mass at my local town church at one pm, immediately followed by a reception at a close by location. What this means is that it will be an hour long and it will have a very ritualistic feeling to it and will be heavily focused on tradition and being formal. The dress code would be more along the lines of going to church on Easter - nice dress/sundress or blouse and slacks for women, and a suit or just a dress shirt for men. I'm going to wear a knee length dress and my FH is wearing a black suit.
However I really hate being the center of attention so the reception will be much more laid back. It will be a the civic center and we're catering Chipotle with some appetizers (for those who don't love burritos) and margaritas. There will be cupcakes but no cake cutting/feeding each other. There also won't be any dancing, best man speech, bouquet tossing, or any of those traditions. It will basically be like big family reunion of 150 people. Is there anything I can say in the invitation to prepare people or do I just need to do whatever I want and ignore anyone who isn't happy with all the tradition-breaking? I'm putting in the invitation "holy matrimony" and "Nuptial Mass" to prepare people for that part but I'm worried it makes it sound like the whole thing is formal and traditional, even the reception
