Hi there! When reporting bugs it's very important you list what steps you've done before leading up to the bug. A description of a dress isn't much information. Are you saying that no matter how many dresses you create, they don't show up in "Outfits"?
However, it sounds to me like an issue with deleting a dress/creating one to replace it and it's showing the old one. It has to do with exiting the game without saving. This issue is fixed in 1.5 (not yet public) but not in 1.4, so please remember to save before you exit the game :)
