Just Steam It!
Completely crease resistant suits have not yet been developed although, I am sure they will come.To help the wrinkles come out and not have to give your suit to the dry cleaners or re iron it, just use some steam applied to the wrinkles and you will see them disappear. You can use steam from a good travel steamer or your home iron. Be liberal with the steam, it cannot hurt the suit.
Note that if you do apply steam, apply it only to the creases and then let your garment dry before wearing it. Remember that steam is really small water droplets and it works by relaxing the wrinkles. When you apply steam you are really dampening the suit and wearing a damp suit will only aggravate the wrinkles.
The golden rule then is to let your steamed suit hang in a well ventilated area until it is completely dry.
