Adding to my wedding dress

So I had to postpone like many of you to next August. We went ahead and had a small marriage in our backyard with just our parents and siblings. It was thrown together last minute so I bought a cheap dress online to wear as mine was not altered to fit. So to help get myself pumped to wear it I was thinking about enhancing it a bit. I want to add optic lights to the skirt (tulle ball gown) to make it glow for our first dance. Not sure how to do so yet but I am a seamstress so I'm not worried about messing up the dress. I just don't do anything with lights. Anyways I'm just super excited! I have also dropped 20lbs and counting since July and I'm excited to put my dress on and see the difference in size!
