off white + multi-coloured knitted sleeveless sweater vest

this is a very unisex piece, it’s labeled as M, but i’m a women’s size S and I enjoy the loose fit is has it drapes very well, making it good for any size from S-L minimal staining near the mouth area but almost looks intentional? I styled this in the summer with loose cotton shorts (because it’s a very breathable piece) and in the winter as a layering piece #80s #y2k #vintagesweater
