CINEMANIA: Guess the movie title

A young woman was preparing for her wedding. She asked her mother to go out and buy a nice long black negligee and carefully place it in her suitcase so it would not wrinkle. Well, Mom forgot until the last minute. So she dashed out and could only find a short pink nighty. She bought it and threw it into the suitcase.
After the wedding the bride and groom enter their hotel room. The groom was a little self-conscious so he asked his new bride to change in the bathroom and promise not to peek while he got ready for bed. While she was in the bathroom, the bride opened her suitcase and saw the negligee her mother had thrown in there. She exclaimed, "Oh no! It's short, pink, and wrinkled!"
Then her groom cried out, "I told you not to peek!"
