Soon to be a FTM!

Ladies this might be a dumb question but I have no idea I hear everyone says babies outgrow their clothes so quickly I just would like an idea on how much clothes to get the baby. For stages like newborn, 0-3,3-6, then I’ll have an idea as I learn but idk if I should skip newborn clothes and go straight to 0-3?

I honestly don’t know how much we’ll need of each thing. Please advice! Thanks.
