To see or wear an evening gown in your dream represents enjoyment, social pleasures, grace and culture.

It also represents the image that you are projecting to others.

Consider the colour and design of the gown for additional significance. If the gown is very fancy or ornate, then it signifies an elaborate and luxurious lifestyle.

If the gown is plain or simple, then it suggests a simplified lifestyle.

Alternatively, to dream you are wearing an evening gown indicates that you are seeking or trying to attain some sense of happiness.
