How many hangers for a baby wardrobe?

Hiya, The wardrobe I am getting for my first child has got two rails, one at the top and one at the bottom, I also have two chests of drawers with 3 drawers in each. I am going to put nappies in a drawer, sleepsuits, vests, and rompers in another drawer, socks, hats tights, knickers, nappy wraps etc.. in another drawer, but I was wondering how many coathangers I would need for my baby wardrobe. I dont want it to be empty, but I was going to put snowsuits, pramsuits, coats, outfits, dresses, christening outfit in the wardrobe. I have already bought two packs of white wooden coathangers so I have 20 so far, how many more would I need to buy? Thanks All
