My DD wanted to add some elements of movies that they loved into their wedding - mostly Disney movies. No one dressed up in costume, but the wedding party (MOH, BM, FGs and parents) all dressed to represent a certain movie. I linked a pic of her and her MOH who was Belle. Her boutique was a basket of flowers with a couple books in it - which just happened to fit her MOH's personality perfectly. You can't see the red rose brooch in the pic that we fastened the sash with. My DH and I were Carl and Ellie. My DH wears "Carl glasses" anyway. He wore suspenders with a bow tie, and I wore a sundress like in the picnic scene. His parents were Lilo and Stitch - which his mom was thrilled about since she is part Hawaiian. She wore a red muumuu with white flowers and he wore a blue Hawaiian shirt. The flower girls were Sebastian and Flounder - red sundress with black trim and yellow sundress with blue trim. We did a Lady and the Tramp style reception with red and white checked tablecloths. The centerpieces were old fashioned wine bottles with a single rose. (We didn't do candles since it was day time....and a fire hazard.) We all had a lot of fun with it. I think it is great how much you can really personalize your wedding now. Hope the pic comes through.
