Got a question about funky translation (maybe) from rakuten, can anyone help me with what this means exactly?

Sleeve and shoulder width plus the length from shoulder to hem: 90cm
That's like 35 inches, which makes me think maybe its from the hem of the sleeve to the line of the opposite shoulder? If its measuring both arms and the shoulders that seems comically small, also wouldn't seem to fit with the body length of the coat which is 94 cm.
Help appreciated
