Women’s size M camisole with adjustable shoulder straps. Armpit to armpit is approx 15” and the length of material from top to hem is approx 19”. There’s no brand, I got this most likely t a consignment boutique many years ago. The tag sys it’s from the 80-90s. I never wore it and my girls would never fit into it now! But it is quite pretty and possibly ‘one of a kind’!
