Casual dresses for rectangles

"Keep the length short or shorter. Minis are made to show off the curve of your legs -- what better way to say, 'I'm a girl!'" says fashion expert and TV personality Jeannie Mai.

Any type of dress that adds definition to your waist is a must-have for rectangle shapes. Avoid sheath dresses with straight lines, but don't choose a dress with a big puffy skirt either -- it will make you look out of proportion.

Gwyneth Paltrow, Keira Knightley, Reese Witherspoon, Kate Hudson, Nicole Richie and many models have rectangle body shapes.
