Striped fabrics are very effective when used in clothing.  A vertical stripe in the body of a garment has a slimming effect.  A horizontal stripe in a yoke gives the illusion of wider shoulders.  Many ready-made shirts are found with bias-cut striped fronts - with the bias in opposite directions to give a chevron effect.  This is a flattering look and drapes nicely too.  Cut the fronts separately to get this effect.  (It takes more fabric!)
