Answer:
There is no formal tradition as it pertains to engagement rings on your wedding day. I have officiated hundreds of weddings, and most brides wear their engagement rings and then have their wedding band slipped on during the ceremony. If, for some reason, the bride does not want to wear her engagement ring due to swelling, glove wearing or simplicity.. she can wear it on her right hand or keep it home. There is an old tale that says that wearing the wedding band first is best because it's "closest to your heart". But you really should wear them the way they look best and feel most comfortable. The symbolism is not changed by the order in which you were them.. the fact that you have an engagement ring and wedding band on your left ring finger is indicative to anyone that you are in a committed, married relationship.
Do what's in your heart and what makes sense for you..and enjoy your wedding!!
Traditionally, wedding ring was to never be removed showing as an eternal symbol of your love and commitment. Because of this, most women slide their wedding band on first at the wedding and later place the engagement ring on top of that. Today most say the wedding band is worn closest to the heart. Many bridal sets and matched rings are soldered together, however, making this a moot point and entirely up to personal preference.
From what I was told Ur supposed to wear your wedding band closest to Ur heart and then Ur engagement ring but u don't have to wear the engagement ring after marriage unless u prefer to. I only wear it when I go some where.
