A common female body shape
A columnar, boxy silhouette that comes from similar circumference of the bust, waist and hips.
Hips tend to be square and often the arms and legs are proportionally slender
A flat bottom is also common
A rectangular woman will often appear shorter and heavier than she really is.
Many women find they become rectangular with age. The thickening of the mid-torso is most commonly a result of the vertebrae compressing and creating less torso length and less space to distribute any fat.
The aim is to add definition to the shape by visually elongating body and defining the shoulders (if you are overweight) or defining the waist (if your are slender).
