Dreams dictionary: Petticoat
Dreams dictionary: Interpretation 1
To dream that you are wearing a petticoat represents your reluctance in revealing something about yourself. You are being modest or conservative about some aspect of your life.
Dreams dictionary: Miller Dream Interpretation
To dream of seeing new petticoats, denotes that pride in your belongings will make you an object of raillery among your acquaintances. To see them soiled or torn, portends that your reputation will be in great danger. If a young woman dream that she wears silken, or clean, petticoats, it denotes that she will have a doting, but manly husband. If she suddenly perceives that she has left off her petticoat in dressing, it portends much ill luck and disappointment. To see her petticoat falling from its place while she is at some gathering, or while walking, she will have trouble in retaining her lover, and other disappointments may follow.
