It's simple - just go thru the alphabet w/ a wedding item that starts with that letter.
I'll start
A - Alcohol, there's no party complete without it (IMHO)
B- Bride, can't have a wedding without her
C - Corset - hope it doesn't squish my back fat over the top
D - Diaphram - you'll need it on the honeymoon
You're next starting with the letter E...
