Baby closet organization

Yes yes, getting ahead of myself. How did you organize your baby’s/babies’ closet? We’re having twins late spring/early summer and I’ve started collecting hand me downs. There are so many different types of things - onesies, swaddles, sleeveless one pieces, hats, etc. Anyone have a foolproof organization method that worked well for them? I’m starting by size but then not sure what should go where!
