Help Me

So, about a year and a half ago, I saw a wedding dress in a friend's wedding magazine that I immediately knew would be my dress. It was close to my bday at the time, and I had found it online for like $150, so I told my mame to get it for me for that bday. This beautiful dress has been hanging in my closet ever since:

But recently I've been perusing a website with ball gown dresses, and I'm second guessing my dress. I still love it and I still want to wear it, so I was thinking...why don't I wear a ball gown dress for the ceremony part, and my original dress for the reception? Sounds like a good idea, right? I mean look at this thing!:

 

Beautiful, right? Arrrggghh I don't know what to do.
