Kids Dream Light blue organza dress with ribbons

Kids dream Light blue organza dress with ribbons and ribbon flowers. Small snags on inside lining but can be repaired and not see when dress is on. No size tag but approx. measurements are pit to pit flat 11.5" Shoulder to waist 8.5" Shoulder to hem 29" waist 11.5" My guess on size would be 6 or 7 since my grand wore this 2 times
