Copper Union Oversized Linen Overalls in Black 1

Great preowned condition
Size 1
Brand website size chart suggests size 1 is 12/14, however they say to size down as these are intended to fit oversized. I would say they probably fit up to a size 18/20

Maybe be an early iteration of the Esther Overall
