Olive green Sleeveless romper jumper jumpsuit

Super cute! Use a belt to cinch in the waist! Beautiful olive color. No size or fabric tag. Feels slinky, smooth and cold to touch. Not exactly to sure of the fabric. Super loose and flowy. I think this can fit up to a large. There is a slight pill pleaser last photo. Approximate measurements: Shoulder to shoulder:20” Pit to pit: 22.5”
