Perfumes in laundry detergent - help!


So my coworker sweetly lent me all her maternity clothes because we're the same size. I washed them all last night and hung them to dry and my husband can't stop sneezing because he's allergic to perfume and they still have a strong perfumy laundry smell after washing.

I think they smell nice, but I need to get the smell out!

Any ideas??
