Girls with broad hips should wear A-line skirts in a bias cut ie the garment is cut at an angle to the warp (horizontal yarns) and weft (vertical yarns) of a fabric. Avoid broad waistbands and pencil skirts.
Skinny girls should wear fuller skirts like a bubble skirt (a voluminous skirt, somewhat resembling a balloon), and avoid pencil skirts and anything, which clings to the body.
Saddled with a paunch? Wear skirts with embroidery on the hem as it takes attention away from the waist. Also team it up with a plunging V-neckline as it makes the torso look slimmer.
Short chicas can choose from monochromatic (single) colours, which give an illusion of height. A-line skirts, which are fitted at the hips, can also make short girls look taller. If one is wearing a belt, it should ideally be of the same colour as the skirt.
