When a couple gets married the bride needs to wear for good luck:
On the day of the wedding, it is bad luck for the groom to see the bride before the wedding ceremony.
As the bride walks down the aisle to her groom, her face is covered by a veil. It is then lifted (usually by her father). This symbolizes her freedom from her parents and the beginning of her new life.
After the wedding ceremony, as the couple leaves the church or after the reception as the couple leaves, the guests toss rice at them. It is a way to wish them well. However, it was found that then birds would eat the rice and it was not good for them to eat the rice. So now, the guests usually blow bubbles at the couple to signify well wishes.
After the wedding, during the reception, all of the single women gather around the bride. Then, she throws the wedding bouquet and someone catches it. It is said that whoever catches it will be the next to be married. I caught one when I was 19 years old, but I didn’t get married until many years later. So, I’m thinking this isn’t true.
