If you have a long chin to mid-bust point and long knee to sole of the foot proportion, but your thigh is short as is your waist, and if both halves of your body are relatively equal, then you may have a balanced body, but with a short mid-body.
Since you have a long decolletage, play it up, wear great jewellery, or put interesting detail and necklines on to draw attention to it.
As you have longer calves, draw attention to your feet with fabulous shoes. Skirt hems can also be detailed to draw the eye to this longer proportion. Keep skirts and dresses around knee length to make your legs look longer.
Keep your shorter mid-body clear of detail. Avoid wide belts. Use empire waist garments to create the illusion of a longer waist.
