Frankie Morello Milan v neck tee shirt top

In very good pre owned condition. No flaws. There is no size tag, but fits like a small/medium. I am not positive it is a woman's style, but it is slim cut through the waist area so I am assuming it is. Shown on a size 4 woman's mannequin. Laying flat, armpit seam to armpit seam measures 18 inches across, top of shoulder to hem is 26 inches.
