Aritzia Sunday Best Size M (XS) Heart cropped wool blend sweater

Heart sweater from Aritzia. Wool blend (wool, alpaca, viscose, nylon) This was my neice's sweater and she is a teen. I am sure she put this in the dryer and it's shrunken so I have provided meaurements. It's labeled a M but sure looks like a SMALL OR XSMALL on my mannequin. See the pics for measurements and my mannequin dimensions are below I did lightly use my sweater shaver but this does still have some pilling. No holes or rips or stains. Mannequin is generally a 0/2 for reference REASONABLE offers always welcomed!
