This NWT vintage Gymboree swing top in kid girls' sizes is made of 100% cotton.  It is a colorblock knit short sleeve top with three gathered tiers to make it closer to a tunic length.  The tiers are white, bright yellow and bright blue. There are three 3D flowers with gem centers at one side of the second tier.
