How to get smoke smell out of clothes?

Anyone know? A little girl gave me some clothes for our unborn daughter... I have washed in dawn, than with regular detergent.. and they still smell like smoke. I don't want to throw them out.. but I refuse to dress my baby in smokey clothes. Her parents are smokers and it cringes me how they smoke with her in the house. Not judging them, just wish they wouldn't do it.
