1950s/60s vintage girl scout uniform

Beautiful uniform purchased from a boutique in NYC. see photos for the only wear and tear-- a pinhole snag and a hand-mended pocket corner. Otherwise pristine and unfaded. Hem looks like it was skillfully basted and pressed to allow for lengthening (see photos). I usually wear a standard US small, and I would consider this a petite XS. 14" from shoulder seam to shoulder seam, 13" across waist (when buttoned and laid flat).
