Around 2007 or 2008, I rented a movie from blockbuster and can’t remember the name for the life of me! It was about a woman who was a bridesmaid or maid of honor and the bride walked in on her hooking up with the groom on their wedding day… the movie winds up being about the ex bride throwing some sort of party and the main character being the Ex bridesmaid/maid of honor being the only one not invited to the party and trying to find a way to get invited. There was one scene where she bought a Stuart Weitzman bag with Dalmatians on it and another scene where she winds up giving it to the ex bride and told her she didn’t keep anything in it. I can’t seem to remember the name of this movie, can anyone help me out? It was from the early 2000s I believe
