Aledo Toile Linen Quilted Jacket Farm Pattern Green White S/M

Gently preloved still on website for $170 I have it as S/M it’s 19” PTP when gently closed in front but I cannot seem to find the size tag. I’m a L/XL and it barely goes on me so I think it might be a small but just incase due to the PTP I have it as small medium.
