I do not have clear understanding of the history of the bridal shower party. And so I tried of searching in the net and these are the informations I found in relation to it. According to "Her Bridal Flavors", the bridal shower is a special event allowing friends and family to spend time with the bride-to-be before the Big Day to laugh, celebrate and enjoy one another's company. This memorable day, which also takes a great deal of planning, is a tradition that truly marks the beginning of wedding celebration and festivities.
The tradition of the bridal shower originated in he United States, although the first story originates from a love affair based in Holland. The story begins with a young girl who fell in love with a poor but good-hearted mill operator. Her father was unhappy that his daughter was planning to marry a penniless man and, in order to dissuade her, refused to give her the customary bridal dowry. Friends and members of the community decided to come together and “shower” the couple with gifts in order to compensate for the dowry and allow them to marry. This romantic gesture quickly became a tradition for all brides and their loved ones.
I believe that different country do have different beliefs when it comes to this.
