Vtg 1940s Princess Peggy Romper W/ Front Zip Sleeveless Rockabilly Floral XS 0/2.  There is no size tag in this vintage 1940s romper.  Using the modern size guide shown in the photos, Please be sure to check out photos 12 and 13 showing where some of the gathering stitch is not intact.  There are no rips or tears.  I have estimated this to best fit a size 0/2 or XSmall.  Please compare your measurements to the measurements in the photos to assure a proper fit.  I have also enclosed a screenshot from the Vintage Fashion Guild's website dating this label to the 1940s.
