Traditionally it is the bride's parents; however, things have very much changed. Often it is the couple who pay for their wedding day if they are working professionals. How much will the wedding cost, what are the traditions within the family, where will be the wedding be located. There is no longer a hard and fast rule for who pays. Some parents split the amount owed or select what they will pay for. The key is not to stress a wedding on cost as it is a celebration. The older the couple ie, early thirty's onwards typically pay for their wedding day.
