It's an approximate modern day medium. I've included measurements to enable you to choose the correct fit for your size:
Chest: up to 36"
Shoulder to cuff: 22"
Shoulder to hem: 19.5"
Please ask if you have any questions :)
Please note: this is a used item, not new and not pristine. My items have been in storage and may require laundering. If there is a problem with your order please contact me straight away - I always work with my customers to try and resolve any issues. Please read the item description and measurements carefully before bidding to try and limit the wastage created by returns in terms of packaging and postage - my mailing bags are recycled but I always try and find ways to reduce the impact on the environment. I do take care to list any noticeable flaws but please bear in mind a small amount of wear is to be expected with vintage garments. Comes from a pet and smoke free home.
