For Kitty Rescue! Old Navy Youth Distressed Denim Jacket

This jacket isn't marked as a youth size, but I'm pretty sure it is, because it's really too small to be an adult XL.  I think it's a youth XL. I wear a size large and I can button it, but it's too tight to be comfortable and the sleeves are a little short.  I think it would fit an adult size small or possibly medium, but please check the measurements!! Measurements lying flat: Armpit to armpit 20.5 Waist side to side 20.5  Hem side to side 20.5 Length from shoulder 20  Sleeves 24 100% cotton, no stretch Classic jean jacket, boxy cut, breast pockets, button closure. Distressed denim, with several spots that look threadbare, and faded areas.  Excellent pre-owned condition  Every penny of this sale goes to support Saving One Life Rescue in Gilbert AZ!  It pays for veterinary care, veterinary supplies and medications to care for rescued kitties with health issues! Please help!
