Here is a vintage 2T Nannette pink and white girl’s dress.  Excellent condition with no stains, holes, rips, etc.  Elastic is still good on sleeves.  The papery tag that gives the fabric content has stiffened over the years and would want to cut it out if using on a child.  Armpit to armpit is 12 1/2 inches.  Length from back neck seam to bottom is 16 inches.  Thanks for looking.
