The sweetest little 1960s children's dress

Beautiful peachy pink gingham print with lacy collar and the prettiest trim and puffy sleeves. Perfect for summer birthdays, church, or Easter! By Primstyle. Seems like it's never been washed or worn, perfect shape. Lay flat measurements: 12" waist, 13" pit to pit, and 24" shoulder to hem. I'd guess it's a modern 4/5
