Going home outfit

Anyone who’s had babies, I’m really struggling with what size pajamas to get baby for his going home outfit. Ive been looking for a special going home outfit for baby but I don’t know whether to get newborn or 0-3 and I don’t want to break the bank buying more than one of the same outfit. I’m currently 35 weeks, there’s a slight chance baby could come early, as I’ve been struggling with high blood pressure. I know a lot of people bring more different sized outfits to the hospital just in case, I’m not really sure what I should do. Any advice?
