I got married almost 2 years ago. Looking back, I would do some things the same, but do other things differently.
Things to spend money on:
Photographer (seriously the most expensive thing for mine)
Honeymoon (my honeymoon is my best memory, not the wedding!
)
Food
Transportation
Things that you can go cheaper on:
Dress and alterations (especially if you know someone)
Decorations
Gifts
FLOWERS (If I had only known!)
THE AMOUNT OF FRIGGIN' GUESTS!
The time of day = the cost of venue (I had a Saturday early afternoon wedding, which makes for cheaper rental and a lighter menu)
If need be, skip the alcohol. I had an open soda/coffee/tea/beer/wine/champagne bar and it was worth it, but not exactly necessary (expensive)
Looking back, I would have had a destination wedding or a cruise wedding with WAY FEWER PEOPLE. I felt all obligated and stuff to invite people and I should have just invited family and close friends. I feel like I had NO TIME to talk to anyone or acknowledge their presence properly. I would have liked it to be more intimate.
