Vintage Navy and White polka dot dress M

Vintage Navy and White polka dot dress. Size is a M. Dress has a high waist and a zip up side. The material is a chiffon, and underneath has a silk/rayon slip. It has ruffles around the waist and a white tie bow in front. Flared skirt. I’m going to guess this dress is dated from the 1950’s. Dress is in GREAT condition! No rips, no stains, no discoloration! The dimensions are approx: 38” length from shoulder, 15” waist, 13” sleeve, 18.5” armpit to armpit. Any questions, please ask!
