Drycleaning, like just about anything in life, should be done in moderation. You do not have to have your tuxedo drycleaned after every time you wear it. Often times, the harsh chemicals used in drycleaning can damage fabric over time. For this reason, try to limit the number of drycleans that you do on your tuxedo. Obviously, if you spilled food or drink on your tuxedo or you were out dancing the night away, a trip to the drycleaner the following day may be a wise decision. Otherwise, simply place your tuxedo in its garment bag and hang it up in your closet after your formal event.
