These are from a small business local to me, they are 100% organic cotton gauze. They don’t have size/fabric tags but they are about the same size as the 3-6 month pants we have so that’s what I labeled them as. The legs roll up well for longer fitting and the fabric is incredibly soft. These were a favorite during my daughter’s butt scooting phase so have noticeable wear on the back. Colors were hard to photograph but are a pale neutral pink and a grey with a slight blue/green undertone.
