WHO PAYS FOR WHAT?

Contemporary: everyone contributes.

Flowers for ceremony and reception site
Rental fee for church or chapel.
Engagement and wedding photographs.
Fees for sexton, organist or soloists.
Rental fees for aisle carpet and other equipment.
Transportation of bridal party to the ceremony and reception sites.
Complete receptions. All food, beverages, music, decorations, gratuities, and other services.
Grooms ring.

Gifts for the bride's attendants.
Hotel lodging for any attendants and friends from out-of-town.
Gratuities to parking attendants.
Bridesmaid's luncheon.
Corsages for mothers, grandparents, special guests.
Groom/family pays for:
Brides engagement/wedding rings.
Marriage License.
Ceremony official's fee (many times the bride’s family will pay this as well.)
(Going-away corsage for the bride if leaving directly on their honeymoon.)
Wedding gift for bride.
Gifts for best man and ushers
Wedding night suite
Rehearsal dinner
Honeymoon
Blood tests
Gloves, ties, and ascots for men in wedding party.
Attendants pay for:
Personal wedding attire.
Personal traveling expenses.
Personal hotel expenses
If you can get an all inclusive deal, that is generally going to be a better option than if you rent an event center, hire a caterer etc. This is because everything is included and you don't have to go the rental route.
Hope this helps. Please let me know if I can be of any further assistance.
