vintage late 50s orange cotton wrap dress w/self fabric buckle

absolutely stunning 50s true vintage wrap dress with attached self fabric buckle closure. would keep if I had the belle poitrine to fill out the top. length is 46.5,” bust is 40,” waist is 28.5” (but could make an inch larger by moving hook & eye closure), hips to 50.” yes, this isn’t cheap, yes, it’s a unicorn. seams are overlocked which initially made me think it was 70s, but overlocks were around in the late 19C, plus, details like double darts at bust, covered buckle, etc are hallmarks of earlier, higher quality manufacture.
