No tags I believe this is a large, but since the tags are missing, please check below measurements for proper fit. Approximate measurements All measurements are with fabric unstretched Pit to pit 21” Length center back from base of hood to crotch 33-1/2” Hips 24” Inseam 27” Length top of shoulder to hem 59” Sleeve length from top of shoulder 24-1/2” Soft, stretchy fabric, not heavy, feels sort of like a lightweight stretchy sherpa Sound does not work, there is no opening and I did not want to cut it open. May just need new batteries, but I can’t be sure since it has no opening. Please see photos for actual condition and description. Thanks for looking!
