K-pop - BTS - Dynamite Hoodie

BTS Dynamite Hoodie Black and multi-color Tag says XL, my daughter said it fits more like a Medium. Last picture shows it laying on top of another (true) XL sweatshirt. I've compared it to a woman's M (8/10) sweatshirt - Dynamite one is slightly wider; and a generic Large - Dynamite is slightly small in width.
