A muslin wardrobe from newborn to 4 years works best with onesies for the early months, rompers and playsuits as babies start moving, and sets or dresses for toddlers. Epic's muslin cotton is double-layer, pre-washed soft, and gets softer with every wash, so pieces hold up and can be reworn across sizes.
We started Epic because we wanted our own kids in something soft and easy to wash, and muslin cotton kept winning. This guide walks through what to put in a muslin wardrobe at each stage, from a newborn onesie to a toddler dress, so you are not guessing what your child actually needs.
