NWOT Disney Long Purple Cardigan Haunted Mansion

NWOT Disney Long Purple Cardigan Haunted Mansion New without tags still vibrant, fluffy, fuzzy and gorgeous, never been worn and very well cared for Open cardigan without buttons Size Medium 27” width 35” length Measurements Are Approximate  Note On Sizing: This cardi is from the Tokyo Disney. I believe it's a US size medium. (I included the tags in the pics) However It feels more like an XL or even an XXL. So I'm wondering if I'm not reading the sizing correctly. Any input I welcome.
