How do you remove the mothball smell from clothing?

The other day I went rummaging through my grandmother’s attic and I found a really cute vintage skirt my mother wore. The problem is that is REEKS of mothballs. I’ve been trying to air it out but the smell is still there. I don’t know if I need to take it to the drycleaners? Or just wait it out? I’d really like to wear it soon, so any suggestions would be helpful!
