mature wedding dresses

I keep having this dream about this movie that apparently my mind has made up where Rihanna is in it and her character is in her last days before her wedding and the friend of a lady who had a seemingly perfect relationship until her boyfriend meets this girl that he has instant, super strong chemistry with on a bus back home. She finds out about this somehow and she understands but don't really want to let him go and he feels the same but he can't ignore that chemistry. The two ladies are a little different. His girlfriend is really stereotypically girly with dresses and heels and makeup most the time while the girl he meets on the bus is like Ellen Page's character in "Juno." They're both great, smart, cool women. The movie tells the story of mature people who understand what's going on but are confused about what to do but... mature wedding dresses

RIHANNA IS IN MY MIND-MOVIE!
