You can't use dynamic clothing without making an animation. That's how the cloth is draped. It's not that hard. Have you tried the tutorials at PoserFashion.net? There are free dresses you can download there, and each comes with detailed instructions.

You could also use conforming clothing instead. (The stuff in the Figures library.) No animation is required. However, you have to make sure that the clothing was designed to fit the character you are trying to dress. A dress made for Victoria won't fit Judy.
