Wedding Flowers
From the earliest times, brides have adorned their hair with wedding flowers and carried bunches of wedding flowers. Traditionally, each type of wedding flower arrangements had a special meaning and significance in and of itself. Wedding Flowers were often thrown at the couple after the ceremony. However today, most brides pick their flowers for color and personal appeal not based on the traditional meaning of particular flowers.
The groom's flower, worn on his lapel, usually matches one of the flowers in his bride's bouquet. This tradition goes back to medieval times when knights wore the colors of their lady in tournaments.
Garter Toss/Bouquet Toss
In parts of Europe during the 14th contrary, having a piece of the bride's clothing was thought to bring good luck. Guests would literally destroy the brides dress by ripping off pieces of fabric. In order to prevent this, brides began throwing various items to the guests - the garter belt being one of the items.

In order to avoid this problem, it became customary in the 14th century for the bride to toss her garter to the men. Sometimes the men would get drunk, become impatient, and try to remove the garter ahead of time. Therefore, the custom evolved for the groom to remove and toss the garter. With that change the bride started to toss the bridal bouquet to the unwed girls of marriageable age.

Shoes on the Bumper
This tradition originated in England during the Tudor period. At that time, guests would throw shoes at the brides and groom as they left in their carriage. It was considered good luck if their carriage was hit. Today, more often than not, it is beverage cans that are tied to a couple’s car instead of shoes. It should also be noted that the English consider it good luck if it rains on their wedding day!
Tying shoes to the bumper of the car represents the symbolism and power of shoes in ancient times. Egyptians would exchange sandals when they exchanged goods, so when the father of the bride gave his daughter to the groom, he would also give the bride’s sandals to show that she now belonged to the groom. In Anglo-Saxon times, the groom would tap the heel of the bride’s shoe to show his authority over her. In later times, people would throw shoes at the couple. Now, thankfully, folks just tie shoes to the new couple’s car.
