Ann Taylor LOFT SPARKLY sweater size Medium?

Reposhing this item I purchased from @delyxgvv5ius42o. Loved it, but it was too small on me. Tag says Large but I am wondering if it shrunk because it is really too tight. Measures approx. 19" armpit to armpit with not much give. Approx. 23" from shoulder to hem. I am listing as a medium. Smoke free home but we do have cats (allergy alert). Questions?
