Famous Rectangles: Audrey Hepburn.
What Works: Boot-Cut Pants; the slim fit at the hips which gives way a wider hems will give you shape. Fitted jacket; a nipped-in waist will give the illusion of curves. Detailed Top; Visual interest on top will add volume to the bust and shoulders, making the waist look smaller in comparison. Flared Skirt; a flirty hem will give the the illusion of an hourglass.
What Doesn’t Work: Dresses that are tight all over and anything unstructured around the waist, like empire-waist tops.
Best era for vintage dresses: 1950s dresses feature a nipped in waist – perfect for rectangles.
