Sorry, I can't give you specific information about the bride hanging out with her ex-boyfriend in her wedding dress. However, I know that there is a movie called Bride Fight, which is a China movie with a release time of 20 15, directed by Chen Guohui and starring Huang Xiaoming and Chen Kaige. I don't know which movie you are talking about, but if you can provide more information, such as the name of the director, the leading role or other plot details, I will try my best to help you find the answer.
