Dr. Fleming has this to say about modern weddings:
Weddings, having lost all sacramental or even religious sense, are now commercial occasions. They are a cross between a football gam, complete with program, and a night in Vegas. The clothes that the groom and groomsmen wear belong to a circus and not to any decent social occasion, and, as you note, a marriage that begins with rented clothes is not a marriage planned to last. I refused to wear formal clothes for my own wedding and bought a tuxedo. To not very rich young men who will not need a tuxedo for a long time, I always suggest a decent dark suit.
