Newborn clothing

Hey guys!!!! I'm trying to figure out how much of my daughters newborn stuff I should wash before she gets here. I have 13 onesies, 4 full outfits, and 5 sleepers. We haven't had our baby shower yet. I'm thinking I'm definitely going to keep what I've bought, so we can save it for our next baby, if that one is a girl too. But would you say I should wash it all now? Or will it be impossible for her to wear all of that?
