The House of Nu-Mode vintage 70s beach poolside top

The House of Nu-Mode vintage beach poolside top. A unique piece. It ties at the front, but be aware that the tie string slides through the hem of the top, so some fashion tape might be needed unless wearing something underneath. I’m not certain of the decade as this company was in business from 1946-1990s, however the style and material feels like 70s. Size tag is missing, but it measures as a medium. The mannequin measures a 37.5” bust and 30” waist. Measurements on the flat are as follows: Length from back collar: 17” Pit to pit across the chest: 17” Across the waist: 15”
