straight

If you have a straight body, you have more or less the same measurements for all three: bust, waist and hips, with not so much of a defined waistline. Hannah has a straight body.  

Assets :

You can wear fitted, mid- to low-rise, or cuffed pants. You can usually pull off quite oversized clothing, especially if the item is baggier on the top and more fitted on the bottom.  You can wear straight slip dresses, but also can create a waist sometimes by wearing garments that create the illusion of a waistline, like high-waisted pants.
