CEREMONY:
Why? Puts emphasis on Bride and Groom
Why? Love is a private matter.
Why? Keeping it a mature, adult affair allows for a relaxing evening, guests and hosts. This also includes wedding party - no ring bearer or flower girl -- that's just really tacky.
Why? Because I shouldn't have to choose.
RECEPTION:
Why? Why is someone going up your skirt in public, not to mention, in front of your family?
Why? Just bad taste. Get something with meaning.
BACHELORETTE PARTY:
Why? You're getting married! You're not on the hunt!
