Creating a special occasion is not a passive act. You can go out to the theater, eat five star, sit back seperated from the event, and have just an okay time.
However, if you approach an event as something "special", by truly treating like it is, you do a great deal to take things out of the everyday. When do you pull out a tux or an evening gown? During events that are meaningful and important in some way.
Restaurants that have chefs who studied for years, have expensive complicated kitchens to run, educated waiters, and beautiful interiors, wanted to take things out of the everyday. They went to grand effort and it is often a miracle that things come together.
So, showing up in a five star restaurant in an evening gown is not about wanting attention. It's about saying "this night we're sharing is special, the place we're going to is special, lets treat today like it's wonderful."
Dressing up isn't suppose to be a chore, it's suppose to be a celebration of life and a moment of pride and expression in your appearance.
I once canceled a date because he wanted to go to the theater - in jeans. I said I would not join someone to a theater in casual clothes. At least dress pants, and a nice shirt. Cuff-links are a nice added touch. He said "You dress up and I'll go in jeans."
Frankly, I don't care what other people do. However, when going to the theatre, I go with people who believe in this same concept, that this matters, and you don't insult the stage by wearing stuff you'd wear at a local hang out bar. I'm not willing to change my standard, if someone insists they can go with someone else.
I understand from the conception of the idea, to the day it hits a stage or is able to tour - is a PHENOMINAL amount of time energy and people. So many people invovled in so many ways, practising themselves to death, and then the night of the show comes and it's over in a few hours - no second chances, all eyes fixed on you.
If you treat every event, and every day with an indifference, sitting back in your seat waiting to be entertained, rather then becoming part of the experience and responsible for your own pleasure: then life is mundane. It's like looking at the world through a dusty window. I consider honouring special moments in life, celebrating as many little things as possible, enriching to one's life.
"To be sensual, I think, is to respect and rejoice in the force of life, of life itself, and to be present in all that one does, from the effort of loving to the making of bread." James A. Baldwin.
I believe it is a show of appreciation and respect to those creating the event, to show up looking like this night is something special. I believe it is a way of telling the people who are joining you, that it is meaningful to share such a pleasureable experience with them.
And sometimes, all it takes is a lover going out of their way to take you somewhere wonderful and/or meaningful and not necissarily 5 star fanciness. So dressing like the time you're sharing is very special shows that it's significant enough to warrant care and thought.
