Love fancy boutique dresses?
I have a spritz bottle of water (i use distilled water so it doesn't get yucky) near my dryer. I spritz the dress down with water and toss in the dryer on low heat/no heat for 10-15 minutes. Pull it out and put on right away or hang up.
It will be wrinkle free and the bonus to my daughter is that it's warm.
