i chose to order a little large so that the jacket waist can easily settle down over my hips and not be too tight and bunch up at my waist when i am riding. you will have to save the custom field in order to see your changes applied to the preview. best answer: hi - the overall height of 13" is from the bottom to the top of the large ring. it spreads most rapidly during spring (when we moved in) and also spreads more if the trunk is chopped down but not fully removed or poisoned. coaches leaving is part of the business.
