Size 45" 117cm on the label but please refer to the actual measurements below. I think this could be worn unisex. Please note the length ad arm length measurement as for taller people this would probably be too short. 

Pit to pit- 24"

Pit to hem- 13"

Pit to cuff- 16.5"

Shoulder to shoulder-  19"

Shoulder to hem - 24"

This jumper is in good condition. Does have a name label stitched in the collar which shows on the outside.
