Tuxedo
To dream of a tuxedo represents the personality that is exceptionally prepared for something. Wanting to look your best for a special occasion. Readiness for a special event or to use your experience. A tuxedo may also reflect using your cultivated experience and skill. You may have been training for something special for a long time. Celebrating a final achievement with your expertise on display. Wanting to to appear the most impressive that you can in a situation.
A tuxedo may be a sign that you want to use your well homed skills or experience. Wanting to prove yourself, make a name for yourself, or establish your reputation. Your personality may be exceptionally ready to impress others.
Negatively, a tuxedo may reflect feelings of being over-prepared or overqualified. Feeling that your exceptional experience or skills can't be used at all. Being ready to impress others with no way to do that. Impatiently waiting to show off how impressive you are.
Example: A man dreamed of being dressed in a tuxedo. In waking life he was finished his work training and felt he was needlessly waiting for a certification form to be allowed to work. The tuxedo reflected his personality being "more than ready" to get to work.
